What’s the velocity of a ball falling with 100 joules of kinetic energy and a mass of 2 kilograms? use the formula, . a. 3 m/s b. 5 m/s c. 7 m/s d. 8 m/s e. 10 m/s

10 m/s

Explanation:

K.E. = 100 J

m = 2 kg

Let v be the velocity of ball.

Us ethe formula for kinetic energy

K.E. = 1/2 m v^2

100 = 0.5 x 2 x v^2

100 = v^2

v = 10 m/s

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.​

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day
