A racquetball with a mass of 1.0 kilograms collides with a racquet at a speed of 30 meters/second. The duration of the collision is 8.0 x 10-3 seconds. The ball moves off with a speed of 40 meters/second in the opposite direction. What is the
value of the force?
1.25 x 103 newtons
Oь
1.40 x 103 newtons
Ос
1.25 x 102 newtons
Od
1.87 x 102 newtons

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.​

the answer to this is proletariats.

hope this : )

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
