Answer:
38 m
Explanation:
Number of turns=N=100
Magnetic field=B=0.50 T
Frequency of the generator=f=60 Hz
Rms value of emf=
We have to find the length of the wire from which the coil is made.
Peak value of emf=
Length of wire=
Substitute the values
Length of wire=
Length of wire=38 m
Hence, the length of wire from which the coil is made=38 m

Answer:
Gravity changes with altitude. as we know The gravitational force is proportional to 1/R2, where R is your distance from the center of the Earth.
eg. The radius of the Earth at the equator is 6400 kilometers.
Let's say you were in a jet at the equator that was 40 kilometers high above the earth's surface.
