This document discusses Archimedes' principle and buoyancy. It explains that objects float if they displace a weight of fluid equal to their own weight, with the upward buoyant force equaling the weight of fluid displaced. Ships float because their shape displaces more water than a ball of the same weight, creating more upward buoyant force. Submarines and fish control their buoyancy through ballast tanks and swim bladders that alter their density. Oil spills are contained by oil's lower density causing it to float on water.

Floating and sinking - NEW.ppt

Objects float if they are less dense than the fluid they are in, while objects sink if they are more dense. Density depends on an object's mass and volume. Ships and submarines are able to control whether they float or sink by changing their overall density, either by changing their mass through adjusting ballast, or changing their volume. Archimedes' principle explains that the buoyant force on an object equals the weight of the fluid it displaces.

Archimedes principle

Archimedes' principle states that when an object is fully or partially submerged in a fluid, it experiences an upthrust equal to the weight of the fluid displaced. This principle explains why objects float or sink based on their density. If an object's density is greater than the fluid, it will sink, and if its density is less than the fluid, it will float. The upthrust force reduces the apparent weight of the submerged object. Applications of Archimedes' principle include determining ship drafts, submarine depths, and fluid densities using instruments like hydrometers.

It allows calculation of fluid density based on measurements of weight changes when objects are submerged.

Lecture 5 2_archimedes_principle

Archimedes was a pre-eminent Greek mathematician and inventor in the 3rd century BC. Archimedes' Principle states that when an object is fully or partially submerged in a fluid, it experiences an upthrust equal to the weight of the fluid displaced. This principle explains why objects float or sink based on their density compared to the fluid. It also applies to balloons floating in air. The key concept is buoyant force, which reduces the apparent weight of an object submerged in a fluid by an amount equal to the weight of the fluid displaced.

Floating and sinking

The document discusses floating and sinking concepts including:
1) Objects float if they are less dense than the fluid they are in and sink if more dense. Density is mass divided by volume.
2) Archimedes' principle states the buoyant force on an object equals the weight of the fluid it displaces.
3) Objects can change their density and therefore floating/sinking by changing their mass like submarines, or volume like ships.

Fluids

This document discusses fluids and fluid mechanics. It defines a fluid as anything that flows, including liquids and gases. It discusses the properties of fluids like density, pressure, viscosity, compressibility, and how these properties depend on factors like temperature. It introduces concepts like Pascal's principle, Archimedes' principle, Bernoulli's principle, and equations like the equation of continuity that relate key variables in fluid flow situations. Examples are provided to illustrate how to apply these principles and equations to calculate things like fluid pressure, velocity, and buoyant forces.

Topic: Buoyancy – Naval Architecture Group 2

Buoyancy is the upward force exerted by a fluid on an object submerged or partially submerged in it. The buoyant force depends on the volume of fluid displaced by the object and the density of the fluid. Objects with densities lower than the fluid they displace will float due to positive buoyancy, while objects with higher densities will sink due to negative buoyancy. The location of an object's center of buoyancy relative to its center of gravity determines its stability in a fluid.

3.5 archimedes 2018

1. The buoyant force on an object depends on the volume of fluid displaced. The greater the volume of fluid displaced, the greater the buoyant force.
2. Archimedes' principle states that the buoyant force on an object equals the weight of the fluid displaced by the object.
3. An object floats when its weight is equal to the buoyant force acting on it in a fluid. The object displaces a volume of fluid equal to its own volume.

ROLE OF DENSITY IN SHIPS AND AIRCRAFT INDUSTRIES

The document discusses the importance of density in the ship and aircraft industries. It defines density and explains that an object's density determines if it will float or sink in water based on Archimedes' principle. Ships are able to float because they displace a volume of water with a mass less than the mass of the displaced water, creating an upward buoyant force. Aircraft carriers in particular float due to their large size distributing their weight across a wide area, balancing water pressure. In aviation, air density affects lift and engine performance, as lower density means lower aircraft performance.

3.5 Archimedes Principle

Archimedes' principle states that the upward buoyant force acting on an object partially or fully immersed in a fluid is equal to the weight of the fluid it displaces. This principle explains how ships float, hydrometers measure density, and submarines control their depth by adjusting ballast tanks to change weight relative to buoyant force. Applications of Archimedes' principle include ships using plimsoll lines to indicate safe loading levels, submarines pumping water in or out of ballast tanks to dive or surface, and hot air balloons floating when buoyant force exceeds total weight.

The principle also applies to objects floating on a fluid, where the weight of fluid displaced equals the weight of the floating object.

Flotabilidad y Principio de Arquímedes

This document discusses buoyancy and Archimedes' principle of physics. It explains that underwater, divers and marine animals experience an upward buoyant force nearly equal to their weight due to water pressure increasing with depth. Objects float if they have a density lower than water, as the buoyant force equals the weight of the displaced fluid. Icebergs also float due to having a density lower than water and occupying a large volume, with only a small portion of their mass above water as buoyancy counters their weight. Worked examples are included to demonstrate these principles.

Flotation.pptx

Forces Acting on Buoyancy
- The buoyant force is caused by the difference in pressure between the top and bottom of an object submerged in a fluid, with greater pressure on the bottom pushing up.
- This upward buoyant force is equal to the weight of the fluid displaced and will cause an object to float if it exceeds the object's weight.
- An object will float if the average density is less than the fluid's density, the upthrust equals the total weight, and enough volume is submerged to displace a large amount of fluid.

Gravitation 2

This document discusses key concepts related to pressure, thrust, buoyancy, and density. It defines thrust and pressure, and explains how pressure depends on area. It describes how fluids exert pressure and buoyant force. It explains that whether an object sinks or floats depends on its density relative to the liquid. Archimedes' principle states that the buoyant force equals the weight of the fluid displaced. Applications include ship and submarine design. Relative density is the ratio of a substance's density to water's density.

Density and buoyancy 8.13 final

This document discusses density and buoyancy. It defines density as mass per unit volume and explains that density determines if a substance will float or sink in water. A substance with a density greater than water (1 g/cm3) will sink, while one with a lower density will float. Buoyancy is described as the upward force exerted by fluids on submerged objects. Archimedes' principle states that the buoyant force equals the weight of the fluid displaced by the submerged object. Examples are given to illustrate these concepts.

Archimedes' principle

Archimedes' principle states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. This principle was formulated by Archimedes of Syracuse and is fundamental to fluid mechanics. The principle allows calculation of the buoyant force on a partially or fully submerged object based on the weight of fluid it displaces. When the buoyant force equals the weight of the object, it will float, as it displaces a weight of fluid equal to its own weight.

Hydrostatics Math Problems

This document contains 4 hydrostatics problems and information about Archimedes' principle. Problem 1 asks about the depth and danger faced by a scuba diver who fails to exhale during ascent. Problem 2 asks about the density of an unknown liquid in a U-tube. Problem 3 asks about the force required to lift an object at the bottom of the ocean. Problem 4 asks about the depth a block is submerged based on its dimensions and fluid densities. Archimedes' principle is explained as the upward buoyant force a fluid exerts on an object equaling the weight of the displaced fluid.

- Water pressure increases with depth due to the weight of the water above pushing down (P1). This is why fish eyes pop out - their bodies are not adapted to sudden changes in pressure (P2).
- Air pressure decreases with increased elevation since there is less air above pressing down. This is why ears pop on planes or mountains as the pressure outside the body changes faster than inside (P3).

Archimedes' principle explained

The document discusses Archimedes' principle and its applications, including how it was discovered, what the principle states, and how it relates to concepts like buoyancy, relative density, and the operation of submarines. It also provides examples of using relative density to check the purity of substances by comparing their measured density to the theoretical density.

archimedes principle

Archimedes was a Greek scientist who discovered the principle of buoyancy, now known as Archimedes' Principle, after noticing that the water level rose when he got into a bath. His work in geometry, mechanics, and understanding of levers helped the Greek army defeat the Romans. Archimedes' Principle states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. This principle is used in ship and submarine design and in instruments like lactometers and hydrometers that measure density. The formula for Archimedes' Principle relates the density of an object to the density of the fluid, allowing calculation of buoyant force without measuring volumes

Signatures of wave erosion in Titan’s coasts

The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS

The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...

Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

The cost of acquiring information by natural selection

This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

- 3. Archimedes Principle States that the upward buoyant force that is exerted on an object immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the object displaces Buoyant Force (N) = Weight of Liquid Displaced = (Mass Liquid x 9.8m/s^2)
- 4. Buoyancy • Definition: The upward supportive force on an object in a fluid • The force of gravity acting downward on a floating object must be equal to the buoyant force of the water acting upwards • If an object sinks, the force of gravity is greater than the buoyant force
- 5. Sinking vs Floating Floating object: Mass of Object (kg) = Mass of Liquid Displaced (kg) Weight of Object (N) = Weight of displaced liquid (N)/Buoyant force (N) Sinking object: Mass of Object (kg) > Mass of Liquid Displaced (kg) Weight of Object (N) > Weight of displaced liquid (N)/Buoyant force (N)
- 7. Example: If 100 kg of water is displaced by a floating object, the buoyant force is equal to the weight of the water. If the weight of the water displaced is 980N, then the buoyant force is also 980N Weight Water = Mass x Gravity (F = m x g) = 100kg x 9.8m/s^2 = 980N
- 8. Shape & Buoyancy • The ball and the ship have the same weight – but the ball sinks & ship floats – why? • Because the shape of the ship displaces more water than the ball (the weight of the water displaced is greater), more upward buoyant force is applied allowing the ship to float
- 9. A boat has a weight of 1000N. When the boat is in water, it can displace up to 500kg of water. 1. Will this boat sink or float? 2. What is the buoyant Force? 3. What is the maximum amount of weight this boat can carry before sinking?
- 10. Buoyancy Applications: Oil & Water • Oil is less dense than water – so it floats on water • Difference in density helps during oil spills • Can scoop, suck or soak up much of the oil on top of the water
- 11. Buoyancy Applications: Fish • Swim Bladder: a controllable, balloon-like chamber that allows fish to alter their buoyancy • By changing amount of oxygen in bladder, fish alter their density and ultimately how much water they displace (changing their buoyancy) • More oxygen in bladder = less dense = higher float • Less oxygen = less dense = more sinking
- 12. Buoyancy Applications: Submarines • Ballast Tanks: Compartments in a ship or submarine that take in water to keep the ship stable or help a submarine dive below the surface
- 13. Boat Challenge Objective: Students will design and build a boat using aluminum foil that can carry the most weight while floating in water. Materials: Aluminum foil Best Design: Awarded to the boat with the most innovative, aesthetically pleasing, and well-executed design. Carry the Most Weight: Awarded to the boat that successfully carries the greatest amount of weight while remaining afloat.
