In professional baseball, pitchers can throw a fastball at a speed of 87 mi/h. (a) given that the regulation distance from the pitcher’s mound to home plate is 36 ft, how long does it take the ball to reach home plate after the ball leaves the pitcher’s hand? 0.2821 s you are correct. your receipt no. is 158-5539 : receipt previous tries (b) it takes (on average) 0.33 s for the batter to get the tip of his bat over home plate. how much time does that give him to react? incorrect. tries 2/5 previous tries (c) the average fast pitch in professional women’s softball is about 58 mi/h, where the regulation distance from the pitcher’s mound to home plate is 23.5 ft. how long does it take the softball to reach home plate? for simplicity, assume the pitcher releases the ball just above the center of the pitcher’s mound.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

it is a negative acceleration

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
