3. A delivery truck starts from rest and accelerates for 18.3 s to a velocity of 22.5 m/s, south. What was its acceleration?

a truck is moving 14 m/s to the south. if it takes the truck 20 seconds to reduce its velocity to 10 m/s south, what is its acceeleration

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.
