2. a ball is tossed straight up into the air with an initial speed of 12 m/s.
a. how long does it take to reach its highest point?
b. how high does the ball rise above its point of release?
c. how long will it take for the ball to reach a point 5.0 m above its release
point? (should have two answers for this explain why)

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..

a, c, d, e are all applying about success strategies.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
