At its lowest setting a centrifuge rotates with an angular speed of ω1 = 250 rad/s. When it is switched to the next higher setting it takes t = 8.5 s to uniformly accelerate to its final angular speed ω2 = 750 rad/s.

answer: the answer is a

the answer is a 3.8cm

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.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
