Explanation:
i think you have to find the velocity by using its wight times the gravity of the earth times the distance it fell?
look in google for a formula the use these sign, w and g ,d
Answer:
As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.
is the period of orbit.
<u>Explanation:
</u>
The equation that is useful in describing satellites motion is Newton form after Kepler's Third Law. The period of the satellite (T) and the average distance to the central body (R) are related as the following equation:

Where,
T is the period of the orbit
R is the average radius of orbit
G is gravitational constant 
Here, given data


Substitute the given values, we get T as



Taking square root, we get

Answer:
350 miles
Explanation:
because multiply 70 times 5 and you will get 350
