A 512Hz tuning fork is used with a resonating column to determine the velocity of sound in water. If the spacing between resonances is 1.46m, what is the velocity of sound in water?

v= 1495.04 m/s

Explanation:

The formula for velocity of sound is given by ;

v= fλ   where

v= velocity of sound

f= frequency of turning fork

λ = wavelength

However,

Δ L = 1/2 λ   where Δ L is spacing between resonances.

1.46 = 1/2 λ

1.46 * 2 = λ

2.92 m = λ

v= fλ

v= 512 * 2.92

v= 1495.04 m/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

we need to know the time interval during which the force acts. impulse of force = momentum change
