8 0

Answer:

23 m/s

Explanation:

The net external force on the propeller is 17N

The airplane is 0.75 kg

Therefore the acceleration of the plane can be calculated as follows

= 17/0.75

= 23 m/s

Hence the acceleration of the airplane is 23 m/s

What is meant by the number of complete oscillation made by an oscillating body in 10 seconds is 500 complete oscillations is that the  frequency of the oscillating body is 50Hz

<h3>What is frequency?</h3>

Frequency of an oscillating body can be defined as the number of complete oscillations per unit time

Frequency is measured in hertz (Hz).

Also, the frequency of 1Hz is one oscillation per second.

frequency = number of oscillations/ time taken

frequency = 500/10 = 50 Hz

Thus, what is meant by the number of complete oscillation made by an oscillating body in 10 seconds is 500 complete oscillations is that the  frequency of the oscillating body is 50Hz
