This document summarizes a study assessing groundwater quality in the Agra-Mathura region of India. Water samples were collected from 6 sites in Mathura and 6 sites in Agra and analyzed for physical and chemical parameters including total dissolved solids, pH, fluoride, and heavy metals. The results showed that total dissolved solids and electrical conductivity exceeded permissible limits at all sites. Fluoride concentrations were extremely high in Mathura, with some locations over 200 ppm compared to the safe limit of 1.5 ppm. Heavy metal levels of lead, chromium, and copper were also found to be higher than WHO limits in many locations. The high levels of pollutants indicate that the groundwater in the region is contaminated

Water pollution is one of the major global environmental problems. It is an acute problem almost in all major rivers and water reservoirs in India. Water pollution is increasing and becoming severe day by day and posing a great risk to human health and other living organisms. There is growing concern on the deterioration of ground water quality due to geogenic and anthropogenic activities. Present investigation aims at insight about the level of contaminants of surface water, groundwater and sediment analysis of selected rivers of Krishna River located in Mahuli and Urmodi river located in Nagthane, Satara district. An attempt has been made to assess the water quality, sediment analysis of the samples. Dissolved oxygen content of the water samples was observed quite well in limits such as in Krishna river Mahuli DO was 27.68mg L and in Urmodi river Nagthane was13.68mg .In the present study, COD value was observed by 720mg l at surface water of Krishna River Mahuliand 1320 mg l at surface water sample of Urmodi river Nagthane. As expected groundwater samples showed values of hardness within a limit. There is an urgent need for more representative samples to be used to go beyond preliminary assessment as reported in the present study for making appropriate recommendations.

Groundwater Quality Assessment in hard rock terrain of Rasipuram Taluk, Namak...

Groundwater is of most important to rural development in many countries of the world. Over exploitation of groundwater has become a major challenge not only to the present civilization and also for the future generations. The main focus of this study is to assess the suitability of groundwater quality for drinking and irrigation purposes in vicinity of Rasipuram block in Tamil Nadu. Groundwater samples from 15 locations were collected from different wells during January 2015 and analyzed for different physico-chemical parameters. The usefulness of these parameters in predicting groundwater quality characteristics were discussed. The quality of groundwater in the study area is fresh to brackish water, moderately hard to very hard in nature. The piper plot shows that the most of the groundwater samples fall in the field of Na+-Cl- and mixed Ca++-Na+-Cl- type. Water quality index rating was carried out to quantify overall groundwater quality status of the area. The WQI for these samples ranges from 37.34 to 650. Hence majority of the water samples are poor to very poor in water quality. The area in general is characterized by hard water, hence is not suitable for drinking purpose. The samples plotted in the piper and USSL diagram were used to understand the chemical characteristic of groundwater for irrigation purposes. However, the values of SAR, Na% and RSC indicate that groundwater is suitable for irrigation purposes. Overall water quality of the study area was found satisfactory for drinking purpose except in few locations and suitable for irrigation purpose. Hence the local government needs to initiate remedial measures.

Seven units make up the fundamental units used to measure the seven dimensions of the world: length, mass, time, temperature, amount of substance, electric current, and luminous intensity. Two supplementary units are also introduced. The document outlines different units for measuring length and defines the dimensions of physical quantities. It concludes by mentioning the least count of instruments used for measurement.

Motion

ELECTRICITY

This document provides an overview of electricity, atomic structure, electric charge, and electric circuits. It defines electricity as the flow of electric charge through a conductor. Atoms consist of protons, neutrons, and electrons, with protons and neutrons in the nucleus and electrons orbiting the nucleus. Protons have a positive charge while electrons have a negative charge. Electric circuits allow the flow of electrons from higher to lower potential through components connected in series or parallel. Key differences between series and parallel circuits are that current is the same but voltage varies in series circuits, while current varies but voltage is the same in parallel circuits.

Purification of Organic Compounds

This document discusses various methods for purifying organic compounds, including sublimation, crystallization, differential extraction, distillation, and chromatography. Purification is necessary to study the structure, physical, chemical and biological properties of organic compounds and must isolate the compound from any impurities. The appropriate purification method depends on the nature of the impurity and the organic compound. Common techniques include sublimation for volatile solids, crystallization using solvent selection and isolation, differential extraction using immiscible organic solvent layers, distillation, and chromatography using adsorbents and mobile/fixed phases.

Electrochemistry

This document provides an overview of electrochemistry and electrochemical cells. It defines electrochemistry as the branch of chemistry dealing with the relationship between electrical energy and chemical change. An electrochemical cell is a device that uses a chemical change to produce electricity or uses electricity to produce a chemical change. The document describes the components of electrochemical cells, including electrodes and electrolytes. It distinguishes between galvanic cells, which produce electricity from chemical reactions, and electrolytic cells, which use electricity to drive chemical reactions. Examples of the significance of electrochemistry include metal refining and batteries.

sound

The document discusses various aspects of sound. It defines sound as a form of energy produced by vibrations that travel through a medium and are detected by the human ear. It describes how sound is produced by vibrating objects and propagated through materials like air, water and steel. It discusses key characteristics of sound including amplitude, frequency, wavelength, velocity and their definitions. It also covers topics like reflection of sound, echo, reverberation, ultrasound, sonar and their uses and applications. The document provides information on the structure of the human ear and production of sound using a tuning fork experiment.

Heat and Temperature

The document discusses key concepts relating to heat and temperature. It defines heat as the spontaneous flow of energy from objects at a higher temperature to those at a lower temperature. Temperature is defined as the degree of hotness or coldness of a body. Different temperature scales such as Fahrenheit, Celsius, and Kelvin are also discussed. The document also covers heat capacity, specific heat capacity, and the various effects of heat such as expansion, changes in temperature and state, and chemical changes.

'work , energy and power'

This document defines and provides examples of different types of energy, work, and their relationships. It states that work is done when a force causes an object to be displaced, and is calculated as the product of the force and displacement. Kinetic energy is the energy of motion, while potential energy depends on an object's position or state, such as gravitational potential energy which depends on height or elastic potential energy from deformation. Power is defined as the rate at which work is done or energy is delivered over time.

Electric motor

An electric motor is a device that converts electrical energy into mechanical energy. It works by passing an electric current through a conductor coil located in a magnetic field, which creates a force on the coil and causes it to rotate. Electric motors are crucial to modern life as they are used in many appliances and machines, powering things like fans, drills, and vehicles. The speed of an electric motor's coil rotation can be increased by strengthening the current, increasing the number of coil turns, enlarging the coil area, or boosting the magnetic field strength.
