The body with mass m = 300 g is hung on the hook of a force gauge. Calculate the force of gravity, the force of tension exerted by the hook on the body and the weight of the body

the answer is 5 g I just thought it up in my head

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..

so easy. just google the electromagnetic waves and it’ll pop up.
