The period of a sound wave is 0.002 seconds. The speed of sound is 344 m/s. whats the frequency

Archy [21]

Answer:

= 500 Hz

Explanation:

A Period of a wave is the time taken for one complete oscillations by the wave particles. It is measured in seconds.

Frequency on the other hand is the number of complete oscillations covered by a wave in one second. It is measured in Hertz.

Period is the inverse of frequency.

That is; Period, T = 1/ frequency, f

T = 1/f and thus; f = 1/T

Therefore;

f = 1/0.002 seconds

= 500 Hz

A horse is working steadily, providing 750 W of output power. How much food energy does the horse need to work for 1 hour, to th

Valentin [98]

Answer:

Under assumption that all food energy that needs the horse is transformed into work, then the horse needs approximately 3 megajoules of food energy to work for 1 hour.

Explanation:

Since horse is working steadily, the power experimented by the horse ( $\dot W$ ), measured in watts, is at constant rate. Then, the work needed by the horse ( $W$ ), measured in joules, is equal to that power multiplied by time ( $\Delta t$ ), measured in seconds. That is:

$W = \dot W\cdot \Delta t$ (1)

If we know that $\dot W = 750\,W$ and $\Delta t = 3600\,s$ , then the work needed for the horse is:

$W = (750\,W)\cdot (3600\,s)$

$W = 2.7\times 10^{6}\,J$

$W = 2.7\,MJ$

Under assumption that all food energy that needs the horse is transformed into work, then the horse needs approximately 3 megajoules of food energy to work for 1 hour.
