Which statement explains how brakes slow down a car
answer
a they apply an angular acceleration in the direction of motion.
b they apply a torque in the direction of motion
c they apply an angular acceleration opposite the direction of motion
d they apply a torque opposite the direction of motion

Acceleration as a Vector

Explanation:

Keep in mind that although acceleration is in the direction of the change in velocity, it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
