The needle of an electric sewing machine makes 10 complete oscillations per second. Determine the period of oscillation of the needle.
These tasks: t (duration of oscillation of the sewing machine needle) = 1 s; n (number of complete oscillations of the needle) = 10 oscillations.
The period of oscillation of the sewing machine needle can be calculated by the formula: T = t / n.
Calculation: T = 1/10 = 0.1 s.
Answer: The sewing machine needle has an oscillation period of 0.1 seconds.
