A stone tied to a string is made to revolve in a horizontal circle of radius 4 m with an angular
speed of 2 radians per second. With what
tangential velocity will the stone move off the
circle if the string cuts?

The tangential velocity is 8 m/s

Explanation:

Uniform Circular Motion

It can be described as the motion of an object in a circle at a constant speed.

As an object moves in a circle, it continually changes its direction.

If the radius of the circle is r and the angular speed is w, then the tangential velocity is:

v = w.r

The stone is revolving in a circle of radius r=4 m with an angular speed of w=2 rad/s. The tangential velocity is:

v = 2 rad/s * 4 m

v = 8 m/s

i guess the game developers wanted to give off a more gamey/cartoony feeling without trying to copy fortnite exactly

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.
