You are designing a generator with a maximum emf 8.0 v. if the generator coil has 200 turns and a cross-sectional area of 0.030 m2, what would be the frequency of the generator in a magnetic field of 0.030 t?

7.1 Hz

Explanation:

In a generator, the maximum induced emf is given by

where

N is the number of turns in the coil

A is the area of the coil

B is the magnetic field strength

f is the frequency

In this problem, we have

N = 200

B = 0.030 T

So we can re-arrange the equation to find the frequency of the generator:

i think the answer is a and b

i wish you luck

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
