So first I put the rev/minute into rev/second and got 158rps which would be frequency...then to get period i did 1/rps which came out to be .006seconds BUT my online homework is saying this is incorrect???
OpenStudy (savy):
@Abhisar am i doing something wrong here?
OpenStudy (abhisar):
You are doing nothing wrong. But your answer is approximate. Try submitting the exact answer.
OpenStudy (savy):
It wants it in only 2 sig figs...so I tried doing 6.0*10^-3 and that didn't work either
OpenStudy (abhisar):
Umm..then I don't see any error here.
