A2500-kg car falls over a cliff and converts 1000,000j of pe into ke. a. how much mechanical energy does the car have throughout the trip? b. how high is the cliff? c. with what velocity does it land?

B is correct makes more sense

where are the vectors ?

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.
