Ideally, if all the magnetic of one winding cuts the other winding, and there isn't any loss in the transformer core or the resistance of the wire, then the voltage across each winding is proportional to the number of turns in its coil.
If you apply 100 V to a winding of 50 turns, then a winding that yields 20 volts
must be wound with
(20/100) of 50 turns = 10 turns
Answer:
2000 mili ampere
Explanation:
1 ampere is = to 1000 miliampere so 2 x 1000 is equal to 2000 miliampere
Answer:
B, he will fly off the other end
Explanation:
there is too much potential energy that transforms into kinetic energy for him to stay on the track.
Both objects move away from the site of the collision, with speeds
and in directions such that the total kinetic energy and vector-momentum
of both of them are equal to the total kinetic energy and vector-momentum
that Object-A had before the collision.
(i)1.5cm
(ii)4.5cm
(iii)10cm
