A uniform disk of mass 19 kg, thickness 0.5 m, and radius 0.5 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.8 s. What is the rotational angular momentum of the disk

The rotational angular momentum is 18.653 kg m²/s

Explanation:

The rotational angular momentum is equal to:

The moment of inertia is equal to:

The angular frequency is equal to:

Replacing:

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
