The function of a capacitor in an electric circuit is to?
Tema [17]

Well let's see:

A). No.  A capacitor doesn't measure anything.

B). No.  The power delivered to the circuit is determined by
              the battery or power supply and all the things in
              the circuit that dissipate energy.  A capacitor doesn't
              do any of these things.

C). No.  If any current actually flows between its plates,
             the capacitor is shot and can't do its job, and
             must be replaced.

D). Yes. A capacitor stores charges on its plates, and
              electrical energy in the field between its plates.

A 1100 kg car starts from rest and accelerates for 5 seconds at 4.6m/s/s how much power does the car generate
SIZIF [17.4K]

Answer:

The power expended by the car during the acceleration is 116.38KW

Explanation:

Power is a term that defines the rate at which energy is expended whenever work is done.

Power can be given as Force X velocity.

Force can be found using the formula:

F = mass X acceleration.

In this case,

F = 1100kg X 4.6m/s2

F = 5060 N

The final velocity, v of the car can be obtained from this formula:

v = u+ at

U = initial velocity = 0 (since the car started from rest)

a = acceleration = 4.6m/s2

t = time = 5 seconds

v = 0 + 4.6 X 5 = 23 m/s

Therefore, the power expended is 5060N X 23m/s=116,380W

The power expended by the car during the acceleration is 116.38KW
