As denizens of the surface of a spinning planet, we are always in uniform circular motion. imagine you are in nairobi (on the earth's equator) at noon on a monday. answer the following questions only considering the rotation of the earth and not the earth's circular motion around the sun. the radius of the earth is 6371 km. a day is 24 hours.
assuming that you are at at theta = 0 rad at noon on monday and moving in the positive direction, what is your position theta in rad on tuesday at 11: 00 am?

6.02 radian

Explanation:

At 12 noon position is zero radian on Monday

at 12 midnight the position is π/2

at 11 am position on Tuesday is 2π/24 x 23 ( after 23 hours ) = 6..02 radian.

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 bal will not change its velocity.
