A Transformer has a primary coil with 650 turns if the output voltage is 500 volts and an input voltage of 200 volts how many terms will be needed by the secondary coil???
260
555
60
1,625

1625

Explanation:

Ns/Np = Vs/Vp

Ns / 650 = 500/200

Ns = 2.5 x 650

Ns = 1625

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.
