The formula for frequency is f = 1/T where f is frequency and T is period in seconds.
You have you period which is 0.008s and that is all you will need to solve or frequency in a wave:
f = 1/2
f = 1/0.008s
f = 125Hz
If its accelerating it will increase velocity in the direction of the acceleration which is perpendicular to the velocity.
Just took the test and the answer is <span>C. 1,314,718.
