Answer:
6.73 × 10⁻⁵
Explanation:
It is given that,
Number of turns, N = 23
Radius of the coil, r = 24.9 cm = 0.249 m
The distance coil axis 31.9 cm, x = 0.319m
Current flowing through the coils, I = 2.49 A
We need to find the magnitude of the magnetic field at a location on the axis of the coils
. The magnetic field of the coils is given by :
Solve for the time it will take to complete a revolution. That is,
0.510 s / 440 revolutions = 51/44000 s
The frequency in Hertz is the reciprocal of this value thus the frequency is approximately equal to 862.75 Hz.
Angular velocity expressed in radians/second
(440 rev / 0.510 s) x (2π rad / 1 rev) = 5420.787 rad/s
The period is the reciprocal of frequency which is approximately equal to 1.16x10^-3 s.

Explanation:
A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.
