An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.220 rev/s . The magnitude of the angular acceleration is 0.920 rev/s2 . Both the the angular velocity and angular acceleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.800 m

Angular velocity = 0.240 rev/s Angular acceleration = 0.917 rev/s² Diameter = 0.720 m (a). We need to calculate the angular velocity after time 0.203 s Using equation of angular motion Put the value in the equation The angular velocity is 0.426 rev/s. (b). We need to calculate the tangential speed of the blade Using formula of  tangential speed Put the value into the formula The tangential speed of the blade is 0.963 m/s. (c). We need to calculate the magnitude at of the tangential acceleration Using formula of tangential acceleration Put the value into the formula The tangential acceleration is 2.074 m/s². Hence, This is required solution.

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

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
