John played a note on his tuba that vibrated the air 120 times per second. If you play the note for 4 seconds, how many times in
the air vibrate?
2 answers:
480
This is this awnser because its 120 a second, for 4 seconds so 4 times 120 = 480.
Well the equation is rate*time=work/distance(in this case total vibrations)
Now we plug in the numbers:
(we know that 120 times per second is the rate because it uses the word per)
(4 seconds is the time because the unit is just seconds)
12*4=48*10=480
120*4=480
The answer is 480 vibrations
Hope this helps :)
