If i wanted to generate a maximum emf of 20 v, what angular velocity (radians/sec, aka hz) would be required given a circular coil of wire with diameter 40 cm and 500 coils? the coil rotates through a magnet field of magnitude 9e-3 t which is directed such that the angle between the area vector and the magnet field vector varies from 0 to 2 π radians. group of answer choices

35.36776 Hz

Explanation:

B = Magnetic field =

= Maximum voltage = 20 V

d = Diameter of coil = 40 cm = 0.4 m

A = Area =

N = Number of turns = 500

= Angular velocity

Maximum emf is given by

The angular velocity would be 35.36776 Hz

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the bal will not change its velocity.
