The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.
Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts
The answer is D.
Stopping on snow and ice may require up to ten times
the distance than normal conditions.
In normal conditions you can drive easily, but when
there is snow, ice, fog, rain, it is difficult to drive. Some people thought a
stopping distance was twice as in normal condition but it can increase up to
ten times in snow and ice.
During the SUMMER in the northern hemisphere, the north pole is tilted toward the sun, making the sun appear higher in the sky.
