Answer:
0 Joules
Explanation:
The work done is given by
where,
F = Force applied
s = Displacement of the object = 0 m
= Angle between the force applied and the horizontal = 0
Work is only observed when there is a displacement.
The work done by me is 0 Joules as I was unable to move it.
The distance quantity/ measurement must be squared.
The shuttles acceleration in the creases as the fuel is burned because the acceleration of the obect as produced by net force is directly proportional to the magnitude of the net force.
Answer:
The car must be moving away from the person.
Explanation:
From Doppler's Effect, we know that when a sound source moves towards a stationary observer, the apparent frequency of that sound increases. While the apparent frequency decreases if the source moves away from the stationary observer.
The audible range of frequencies for a human ear is 20 Hz to 20000 Hz. Therefore, in order for the sound of a loud speaker to be audible for the person, the frequency must decrease below 20000 Hz.
<u>Due to this reason, the car must be moving away from the person.</u>
