The Mantle lies underneath the crust.
Answer:
You could conclude the 2nd fact
Explanation:
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
