Question

A turntable is spun at 75 RPMs. Calculate the time for each rotation (i.e. calculate the period). Give your answer ...
in terms of seconds. Do not include units in your answer. They will be assumed to be seconds.
to a precision of hundreths of a second. Use a format like #.## in your answer.
to an accuracy of 0.02 sec. Answers within 0.02 seconds of the correct answer will be tolerated.

Answer 1

75 rpm = 75/60 rps

            = frequency

 

Time period = 1/ frequency

 

                    = 60/75

                    =0.8 sec
