A person of 85 kg is in an elevator. if the elevator is moving at a speed of 5 m/s, what's the person's kinetic energy?keep 4 significant figures

The kinetic energy of the person would be 1062.5J

Explanation:

Given:

Mass of the person, m = 85kg

Velocity, v = 5m/s

Kinetic energy, KE = ?

We know,

Substituting the value in the equation:

Therefore, the kinetic energy of the person would be 1062.5J

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.​
