Auniform disk with a mass of 5.0 kg and diameter 30 cm rotates on a frictionless fixed axis through its center and perpendicular to the disk faces. a uniform force of 4.0 n is applied tangentially to the rim of the disk. what is the angular acceleration of the disk?

Angular acceleration of the disk will be

Explanation:

We have given mass of the disk m = 5 kg

Diameter of the disk d = 30 cm = 0.3 m

So radius

Moment of inertia of disk is given by

Force is given by F=4 N

Torque is given as

We also know that torque is given by

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
