The tip of a pinwheel is 0.24 m from the center. the pinwheel spins 5 times each second. what is the tangential speed of the tip of the pinwheel?
0.30 m/s
1.2 m/s
1.5 m/s
7.5 m/s

7.5 m/s

Explanation:

the amount of current in the coil

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.
