- If there is a cool wind blowing, what would be the consequences, as far as heat loss from the body is concerned, of wearing wet clothes? Explain your answer.
- Cloudy nights are usually warmer than cloudless nights. Why?
Homework Answers
if cool wind is blowing, then water droplets on wet clothes will evaporate and for the water drop to evaporate, it need latent heat of energy. so latent energy is provided by the body. so body lose heat energy and and body temperature drops.
cloudy nights are warmer because during day, sun heats the earth and during night, earth loses that heat in form of radiations. but if it is cloudy night then clouds act as insulator and heat is not escaped from earth so it remains warmer.

There are many far-reaching consequences of global climate change. One possible consequence is the increase in the temperature of water. Some organisms are not able to regulate their internal temperatures. Think about the effect that an increase in stream/lake/ocean temperature would have on enzymatic reactions in organisms that cannot regulate their internal temperatures. Salmon and trout are cold-water fishes that may be very susceptible to the consequences of global climate change. They thrive in cold streams with temperatures that range...

The Consequences of Whistle-Blowing This activity is important because, as a manager, you need to reinforce positive behaviors. Whistle-blowing is considered an “especially ethical” behavior because it exceeds normal standards of morality. The techniques of reinforcement theory can be used to encourage behaviors such as whistle-blowing, and may help explain why people may or may not want to report ethical violations. The goal of this exercise is to demonstrate your understanding of reinforcement theory by reading a case and responding...

It is claimed by wind-playing orchestral/band musicians that as their instruments warm up the pitch (frequency) of the notes played by the instrument goes up by a noticeable amount. (That is one of the reasons why wind players warm up before they perform.) Evaluate this claim. If it is reasonable, why? If it is not reasonable, why not? Explain your reasoning using your physics knowledge. If you are at a loss as to how to start thinking about...

1.There has been steady opposition to the deployment of wind turbines in many parts of rural Ontario. Use the Internet to find out about the arguments that are frequently made by local residents who are against the installation of wind turbines. Summarize those arguments (cite your sources). Given that, to date, no scientific study has linked wind turbines with health effects other than annoyance, how much weight would you give these arguments if you were in charge of the decision?...
