This document proves that if two chords AB and AC of a circle have their bisector of the angle BAC as a diameter, then the chords AB and AC are equal in length. It shows that triangles AMO and ANO are congruent since they share an angle and are on the diameter, meaning their bases AM and AN are also equal. Since the perpendicular from the center cuts chords in half, this means that AB and AC must be equal.
Triangle
The document discusses triangles and their properties. It defines a triangle as a closed figure formed by three intersecting lines with three sides, three angles, and three vertices. Two triangles are congruent if corresponding sides and angles are equal. There are five rules for triangle congruence based on sides and angles: SAS, ASA, AAS, SSS, and RHS. Inequalities in a triangle relate side lengths to opposite angles - the longer the side, the larger the opposite angle, and the third side is always smaller than the sum of the other two sides. The document was prepared by Vyom Bhardwaj, a student in 9th B with roll number 37.

AB and AC are two chords of a circle that meet at point A. AD is the bisector of angle BAC and intersects the circle at M and N. Since AD bisects angle BAC, the two angles formed at A are equal. Additionally, the angles formed by the radii to the chords are right angles, making triangles AMO and ANO congruent. Therefore, the midpoints M and N of the chords AB and AC respectively must lie on the same radius, implying that AB and AC are equal in length.

Damped oscillations are oscillations with drag force acting on the system, causing the amplitude to decrease exponentially over time. The oscillation frequency depends on the natural frequency, mass, and drag constant. In an underdamped oscillator, the natural frequency is greater than half the drag constant divided by the mass, resulting in a positive oscillation frequency and decreasing amplitude oscillations. Critically damped oscillators have a natural frequency equal to half the drag constant divided by the mass, reaching equilibrium without oscillations. Overdamped oscillators have a natural frequency less than half the drag constant divided by the mass, with no oscillations and a long time to reach equilibrium.

Longitudinal And Transverse Waves
There are two main types of waves: longitudinal waves and transverse waves. Longitudinal waves involve compression and rarefaction of the transmitting medium, while transverse waves involve oscillation perpendicular to the direction of travel. Polarization is evidence of the transverse nature of waves - polarizers can absorb waves with certain orientations. Many applications make use of the polarized nature of transverse waves, such as sunglasses reducing glare from reflected light and polarizing filters increasing contrast in camera lenses.

Longitudinal and transverse waves
Waves can be transverse or longitudinal. Transverse waves have vibrations perpendicular to the direction of travel, like water waves. Longitudinal waves have vibrations parallel to travel, like sound waves. The characteristics of all waves include amplitude, wavelength, frequency, period, and speed. Wavelength is the distance between two peaks, frequency is the number of waves passing a point per second, and speed equals wavelength times frequency.

CBSE Class IX Sciense Physics Sound
Sound is a travelling wave that is an oscillation of pressure transmitted through a medium. Humans can hear sounds between 20-20,000 Hz. Sound speed depends on the medium and is faster in solids than liquids and gases due to closer particle packing. Noise is an unwanted sound that can cause hearing damage at high volumes. The ear detects sound waves which are then transmitted to the brain. Properties of sound waves include wavelength, amplitude, and frequency which determine pitch. Ultrasound has a frequency above human hearing range.
Sound Waves

The document describes the movement of travelling waves through a medium. It defines key concepts such as pulses, displacement, and speed. It provides an analogy of a wave moving through a crowd at a sports game. The key equation given relates the displacement of a point on the medium to the distance and time: D(x,t) = D(x-vt). It then works through an example problem applying this equation to find the displacement of a marked point on a rope at a given time, as well as determining when the maximum displacement occurs for a different point. Finally, it discusses how the speed of a wave depends on the tension and linear mass density of the medium.
derivation of Wave equation
This document discusses the wave equation and properties of one-dimensional waves. It begins by defining the wave equation as a hyperbolic partial differential equation. It then derives the one-dimensional wave equation mathematically by taking the double derivatives of a wave function with respect to position and time. The key result is that the second derivative of the wave function with respect to position equals the inverse velocity squared times the second derivative with respect to time. It then discusses the differences between traveling waves, which transport energy and move crests/troughs, and standing waves, which remain in a fixed position with nodes and antinodes.

2) When unstressed, photoelastic models are isotropic, but stress causes temporary birefringence by changing refractive indices along stress directions.
3) Relative retardation between light components is measured using polariscopes and relates to stress difference through the stress optic law and material properties.

Diffusion vs drit urrent
Diffusion is the process by which particles spread out from areas of high concentration to low concentration using only thermal motion. When particles are charge carriers in a semiconductor, their motion results in a diffusion current. Diffusion current occurs even without an electric field and depends on the diffusion coefficients Dp and Dn and the gradient of carrier concentrations p and n. The direction of diffusion current also depends on the change in carrier concentrations with position rather than the concentrations themselves.

Two derivations are shown - one for longitudinal waves in solids using Newton's second law, Hooke's law, and a material law applied to a chain of masses and springs; the other for longitudinal waves in air using these same laws applied to changes in pressure and density in a small gas volume. Both derivations result in the same wave equation, describing longitudinal wave propagation as a function of position and time.

Position can be described as either relative or absolute. Relative position depends on the reference point used, while absolute position considers one point as fixed. Motion is defined as a change in position over time, while an object at rest has no change in position over time. Graphs can show the relationships between different quantities like distance, displacement, speed, velocity, and acceleration. The slope of various graphs like distance-time and velocity-time graphs provide important information about rates of change like speed, velocity, and acceleration. Motion can be uniform, non-uniform, or uniformly accelerated depending on whether the rates of change are constant or varying over time.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 1. Quick Guide to Understanding the Relationship between Displacement and Pressure in Sound Waves Ϟ Quick facts Ϟ • The graphs of pressure change and displacement against (linear) position are out of phase by 𝝅 𝟐 • The pressure change described above is the compression and expansion of a medium as sound travels through it • The displacement described above is the displacement of the particles of the medium (left or right) as the result of the said compression and expansion
- 2. … But wait, why? Based on a quick guess, it would be superficially logical that we would think the greatest change in pressure would be the point with the greatest displacement, because it would indicate the greatest amount of movement—therefore greatest change.
- 3. Not quite. Consider the following series of annotated pictures: High pressure : lots of particles crammed into one spot Low pressure: very few particles in the area (relative to the high pressure area anyway) Representation of the particles in a sound wave Ϟ Recall Ϟ Sound waves are longitudinal waves Ϟ Molecules are displaced parallel to the direction of the wave’s propagation
- 4. Particles here at HP actually came from A & B … Which means that particle A’s displacement is +x and B’s displacement is -x at high pressure (HP). And since HP is right in between the two directions of displacement, the displacement at HP must equal ZERO. Let’s plot this specific position (the HP point) on two separate graphs of arbitrary values. Let X1 be the HP point: A B
- 5. … But what about low pressure? How does displacement relate, then? A B The particles at A and B—which are right next to LP—are displacing in opposite directions: -x for A (left) and +x (right) for B. Displacement at LP then, must be ZERO as well. Let’s plot these on the previous graph and see what it looks like. Let X2 be LP: Point of lowest pressure in the wave (LP)
- 6. Since both graphs are sinusoidal, it’s time to connect the dots and really show how the graphs of displacement and pressure change versus position are out of phase with each other, like so: Where displacement is 0, pressure change is at its maximum or minimum, much like two cosine (or sine) graphs with a phase difference of 𝜋 2 .
- 7. … But perhaps you might be wondering, “How do you know which the displacement graph is going? Why can’t it be the other way around?” As in: Why instead of ? This is because as you go from high pressure (x1) to low pressure (x2), the particles in that section are displaced in the negative direction, not the positive direction (recall that X1 is HP and X2 LP): HP LP This particle is (displaced) from this spot: since the particle moved left, displacement is -x
- 8. Hope that clarifies the concept of how and why the graphs of pressure change and displacement are out of phase with each other! Because I sure was confused at first. HAPPY STUDYING!
