Arectangular coil with sides 0.10 m by 0.25 m has 500 turns of wire. it is rotated about its long axis in a magnetic field of 0.58 t directed perpendicular to the rotation axis. at what frequency must the coil be rotated for it to generate a maximum potential of 110 v?

15.2 rad/s

Explanation:

A = Area of the rectangular coil

Area of the rectangular coil is given as

A = 0.10 x 0.25

A = 0.025 m²

B = magnetic field in the region = 0.58 T

N = Number of turns = 500

w = frequency at which coil must be rotated

E = maximum induced potential = 110 volts

Maximum induced potential is given as

E = N B A w

inserting the values

110 = (500) (0.58) (0.025) w

w = 15.2 rad/s

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
