A nuclear power plant produces power with a current of 15.0 kA. A transformer with 500 windings in the primary circuit and 1700 windings in the secondary circuit is used to step up the potential difference to 198 kV. Calculate the power the nuclear plant produce. Assume no energy is lost in the transformers.

873 MW

Explanation:

Find the voltage in the primary circuit.

Vp / Vs = Np / Ns

Vp / 198 kV = 500 / 1700

Vp = 58.2 kV

Calculate the power.

P = VI

P = (58.2 kV) (15.0 kA)

P = 873 MW

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
