A boy is whirling a stone at the end of a string around his head. The string makes two complete revolution every second, and the tension in the string is T. The boy decreases the speed of the stone, keeping the radius of the circle unchanged, so that the string makes one complete revolutions per second. What happens to the tension in the sting

answer: (431,2)

step-by-step explanation:

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.
