During the spin cycle of your clothes washer, the tub rotates at a steady angular velocity of 33.3 rad/s. Find the angular displacement of the tub during a spin of 77.5 s, expressed both in radians and in revolutions.

The angular displacement of the tub will be 2580.75 rad or 411 revolutions.

Explanation:

We know the relation between angular velocity (), the angular displacement () and time () is given by

Given = and the time () required to complete a spin is 77.5 s.

Therefore, the required angular displacment () is

Also we know that,

So, the angular displacement of the tub will be 2580.75 rad or 411 revolutions.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
