When the spring is released, A. The two masses receive equal magnitudes of momentum. B. The two masses receive equal amounts of kinetic energy from the spring. C. The heavier mass gains more kinetic energy than the lighter mass. D. The lighter mass gains more kinetic energy than the heavier mass.

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..
