A music performance takes place in an enclosed arena. A person sitting a distance of 20.0 m from the speaker experiences a sound intensity of 0.32 W/m2. What is the power of the speaker? (Assume that the area over which the speaker transmits sound is given by A = 4πd2, where d is the distance from the speaker.) A.
100 W
B.
550 W
C.
1,200 W
D.
1,600 W

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
