If the frequencies of two component waves are 24 hz and 20 hz, they should produce beats per second. a. 2 b. 4 c. 8 d. 12

B. 4

Explanation:

Beat frequency (fb) is calculated as follows:

fb = |f1 - f2|

where f1 and f2 are two sounds frequencies, in this case, 24 Hz and 20 Hz. Replacing in the equation:

fb = |24 - 20| = 4 Hz

Then, they should produce they 4 beats per second

another example of kinetic energy would be,

kinetic energy   >     moving energy
