Which of these would best define sound intensity? a) how fast the wave is traveling b) the frequency of the sound wave c) the power of the sound wave per unit area d) the mass of the wave divided by its volume

Sound intensity =  The power of the sound wave per unit area

Explanation:

Sound intensity is defined as the the power of the sound wave per unit area. Mathematically, it is given by :

P is the power

A is the area

It is also defined as the amount of energy flowing per unit time per unit area of cross section.

The SI unit of power is watts and the SI unit of area is m². So, the SI unit of sound intensity is W/m². Hence, the correct option is (C).

cancer risk hope this

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
