How many turns is required to be wounded in secondary coil if the primary coil consist 2000 turns with 22 AWG copper wire? Input Voltage = 220V ,Input Current = 1A. transformer is expected to work with 90% efficiency & expected to get 12V 5A output.​

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
