In flight, a rocket is subjected to four forces; weight, thrust, lift, and drag. Forces are vector quantities that have both a m
agnitude
and a direction. Imagine that the rocket is about to lift off the launch pad. According to Newton's third law of motion, what force is
critical to the success of its upward motion?
A)
drag
B)
Lift
c)
thrust
D)

Answer:
1:2
Explanation:
It is given that,
Initial RMS AC voltage is 100 V and final RMS AC voltage is 200 V.
We need to find the ratio of the number of turns in the primary to the secondary for step up transformer.
For a transformer,
So,
So, the ratio of the number of turns in the primary to the secondary is 1:2.
