The tangential speed of the satellite is m/s

12,566 not 12560 because edgenuity doesnt want you to round by the tenths only by the ones

Explanation:

Because 2* pi * 4x10^10 = 251327412400 (Dont round the pi to 3.14)

and divide it by 2x10^7

you get 12,566.37 which its 12,566 (and dont add punctuation, stated on the quiz)

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..
