Fed [463]

Answer:

983.400345675 hits per second

Explanation:

Radius = 14.2 cm

Record turn rate = 33 rev/min

Bump separation = 0.499 mm

Circumference of the record = 2\pi 0.142=0.89221231362\ m

Number of bumps in the groove = \dfrac{0.89221231362}{0.499\times 10^{-3}}=1788.0006285\ bumps

The rate which the bumps hit the stylus = 33\times\dfrac{1788.0006285}{60}=983.400345675

The rate at which the bumps hit the stylus 983.400345675 hits per second
