These tasks: n (the number of revolutions that the electric motor shaft made) = 500 revolutions; t (duration of rotation of the motor shaft) = 10 s.
The frequency of rotation of the motor shaft can be determined by dividing the number of its revolutions by the rotation time: ν = n / t.
Calculation: ν = 500/10 = 50 rev / s.
Answer: The rotational speed of the motor shaft is 50 r / s.
