Calculate the efficiency of an engine if the work input is 300. J and the work output is 100. J

33.33%

Explanation:

take efficiency =power output/power input multiply by 100%

electrical to thermal

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..
