5) A 20kg block is pulled by a 300N force while experiencing 200N of friction. How quickly will it accelerate? 10 m/s/s
0.1 m/s/s
20 m/s/s
5 m/s/s

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..

the answer is to check all of them! they all apply well at least i think so!

positive reinforcement? ?
