5- A jar of (80 cm2 ) cross section area , contains some water till (15 cm) height . Find the pressure that the water exerted on the bottom (base) of the jar .

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 closer the planet is to the sun, the larger the gravity

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
