A generator uses a coil that has 110 turns and a 0.42-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made.

44 m.

Explanation:

Given,

Number of turns, N = 110 turns

Magnetic field, B = 0.42 T

frequency, f = 60 Hz

emf rms value = 120 V

Now, Peak emf calculation

Now, Total length calculation

L = 44 m(approx.)

Length of the coil is equal to 44 m.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

that would be because of both gravity and friction. so     c
