The temperature in a room is 56°c. what would the velocity of a sound wave be at this temperature?

a. 265.2 hz
b. 1856.2 hz
c. 364.6 hz
d. 459.2 hz

C

Explanation:

The units of velocity are m/s, not Hz.  Make sure you wrote it correctly.

The speed of sound in air at sea level is approximately:

v ≈ 331.4 + 0.6 T

where v is velocity in m/s and T is the temperature in Celsius.

At 56°C:

v ≈ 331.4 + 0.6 (56)

v ≈ 365 m/s

The closest is C.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
