A tired squirrel (mass of approximately 1 kg) does push-ups by applying a force to elevate its center-of-mass by 5 cm in order to do a mere 0.50 Joule of work. If the tired squirrel does all this work in 2 seconds, then determine its power.

Power = 0.25 Watts

Explanation:

Given:

Work done = 0.50 Joule of work

Time taken = 2.0 second

Find:

Power

Computation:

Power = Work done / Time taken

Power = 0.50 J / 2

Power = 0.25 Watts

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
