g A cylinder of length 2.75 m, radius 0.420 m, and mass 14.7 kg is rotated at an angular speed of 3.70 rad/s around an axis parallel to the length of the cylinder and through its center. Find the magnitude of the cylinder's angular momentum.

4.792 kgm²/s

Explanation:

Given that

Length of the cylinder, l = 2.75 m

Radius of the cylinder, r = 0.42 m

Mass of the cylinder, m = 14.7 kg

Angular speed of rotation, v = 3.7 rad/s

The magnitude of a cylinders angular momentum is given by the formula

L = I * v, where

I = moment of inertia about the axis given by mr²/2

I = (14.7 * 0.42²) / 2

I = 2.59 / 2

I = 1.295 kgm

L = I * v

L = 1.295 * 3.7

L = 4.792 kgm²/s

Therefore, the angular momentum of the cylinder is 4.792 kgm²/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.
