Explanation:
this is a physical property
Answer:
a force
Explanation:
a force causes a certain object to move and make a displacement.
<span>You are given two cars, one in front of the other, that are traveling down the highway at 25 m/s. You are also given a frequency of 500 Hz of the car travelling behind it. You are asked what is the frequency heard by the driver of the lead car. This problem can be solved using the Doppler effect
sound frequency heard by the lead car = [(speed of sound + lead car velocity)/( speed of sound + behind car velocity)] * (sound of frequency of the behind car)
</span>sound frequency heard by the lead car = [(340 m/s + 25 m/s)/(340 m/s - 25 m/s)] * (500 Hz)
sound frequency heard by the lead car = 579 Hz
Answer:
Explanation:
As we know that for a satellite the force of gravitation is equal to the centripetal force
so we will have
so we know that kinetic energy is given as
so we have
now for time period we know
from above expression of kinetic energy we have
so we have
so square of time period is given as
