"Period" and "frequency" of waves and oscillations are simple reciprocals. They're not related to the wavelength or speed.
Period = 1 / frequency
Period = 1 / 23.4 Hz
<em>Period = 0.043 second</em>

Answer:
the work required to turn the crank at the given revolutions is 8,483.4 J
Explanation:
Given;
torque required to turn the crank, T = 4.50 N.m
number of revolutions, = 300 turns
The work required to turn the crank is given as;
W = 2πT
W = 2 x 3.142 x 4.5
W = 28.278 J
1 revolution = 28.278 J
300 revlotions = ?
= 300 x 28.278 J
= 8,483.4 J
Therefore, the work required to turn the crank at the given revolutions is 8,483.4 J
