B. It is inversely proportional to the square of the distance of the listener from the source.
C. It is directly proportional to the square of the distance between the listener from the source.
D. It is inversely proportional to the distance between the listener from the source.
Answer : The correct option is, (B)
Explanation :
There is a direct relation between the loudness of sound and the intensity of sound.
..........(1)
where,
L = loudness of sound
I = intensity of sound
= intensity of reference
From this we conclude that the loudness is directly proportional to the intensity of the sound.
There is an indirect relation between the intensity of sound and the distance of the listener from the source.
...................(2)
From this we conclude that the intensity of sound is inversely proportional to the square of the distance of the listener from the source.
From equation (1) and (2) we conclude that the loudness of sound is inversely proportional to the square of the distance of the listener from the source.
Hence, the correct option is, (B)
Sun has the greatest gravitational force.
To find the answer, we need to know about the gravitational force.
Thus, we can conclude that as the sun has more mass than that of earth and moon, so it has more gravitational force.

Both students do the same amount of work, but Ben delivers more power due to completing the work in a shorter time.
In this case, both Ben and Bonnie are lifting the same 50 kg barbell over their heads, but they are doing it at different rates. Bonnie lifts the barbell 10 times in one minute, which means she is doing the work over a longer period of time. Ben, on the other hand, lifts the barbell 10 times in 10 seconds, doing the work in a shorter amount of time.
The amount of work done is equal to the force exerted multiplied by the distance moved. Since the mass and distance are the same for both students, the work done is equal. However, power is defined as the rate at which work is done, which is calculated by dividing the work done by the time taken to do it. Since Ben completes the work in a shorter period of time, he delivers more power than Bonnie.
Therefore, Ben does the most work and delivers the most power.
