Try this out. use a calculator! we can use the formula ke=0.5m*v^2. to find the kinetic energy (ke) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (multiply 0.5 x the mass x velocity squared.) your answer will be in joules (a measure of energy). question 3 options: . question 3 options: 5500 j 151250 j 302500 j 2750 j

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..

d is the correct answer
