Answer:
1.25 turns
Explanation:
From Transformer equation,
Ns/Np = Vs/Vp............................ Equation 1
Where Ns = Secondary turns, Np = Primary turns, Vs = secondary Voltage, Vp = Primary Voltage.
make Ns the subject of the equation 1
Ns = NpVs/Vp.......................... Equation 2
Given: Np = 100 turns, Vp = 120 V, Vs = 9600 V
Substitute into equation 2
Ns = 100(120)/9600
Ns = 1.25 turns.
Hence the are 1.25 turns in the secondary coil = 1.25 turns
10 degrees, because 0 degrees will receive the most sunlight, and 10 degrees is closest to 0 degrees.
Answer:They may cause motion to change
Explanation:They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
Answer:
B. Kinetic energy.............
Answer: young's modulus
Explanation: A very rigid material—one that stretches or compresses only slightly under large forces—has a large value of young's modulus .
