Which layer of the Earth is affected by air pollution? ozone layer What if we completely destroy the quality of our air? Air pollution affects all things. It is harmful to our health, and it impacts the environment – reducing visibility and blocking sunlight, causing acid rain, and harming forests, wildlife, and agriculture. Greenhouse gas […]

What does a sharp knife cut better than a blunt one? The pressure exerted by the sharp knife edge is more than that exerted by the blunt one because the area on which force is exerted with a sharp knife is very small. Thus, it is easier to cut with the former than with the […]

What is the application of third law of thermodynamics? The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by ‘S’, is a measure of the disorder/randomness in a closed system. All the atoms and molecules in the […]

How is data sent through wires? Originally Answered: How data is transmitted through wires in the computer ? Most simply, by pulses of electricity. This is a crude analogy, but think of a light switch. You flip it on, and it sends electricity down the wire to the light. Which system uses digital transmission? Which […]

What would happen if the population of rabbits increased? There would be more food for the rabbits and slugs, so their populations would increase. However, there would be less food for the frogs and voles, so their populations would decrease. This means less food for the foxes and hawks. How did doubling the rabbit population […]

What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K Brainly? What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K? 0.715 kPa. Which describes the volume of 1 mol of gas at standard temperature and pressure quizlet? Which describes the […]

Can a gas change shape? A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container. In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little […]

How do I check my Etabs time period? The time period (the one-story model of the structure is below) calculated manually by using the equation in IS 1893: 2016 is 0.170963 and that given by Etabs 2017 is 0.171 (highlighted in the picture below). How do you calculate time period of vibration? As the frequency […]

What is the best anti-vibration material? Rubber Where are vibration isolators used? Vibration Isolation Pad Mounts Pads or sheets constructed of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials are often used under heavy machinery, under common household items, in vehicles and other applications to reduce noise and vibration transmission. What […]

What is wet lab skills? A wet lab is one where drugs, chemicals, and other types of biological matter can be analyzed and tested by using various liquids. On the other hand, a dry lab environment focuses more on applied or computational mathematical analyses via the creation of computer-generated models or simulations. What are some […]
