Q. A teenager pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 20 rpm in 8.0 s. Assume the merry-go-round is a uniform disk of radius 2.5 m and has a mass of 1000 kg, and two children (each with a mass of 20 kg) sit opposite each other on the edge. Calculate the torque required to produce the acceleration, neglecting frictional torque.

What force is required at the edge?

Q. Light is an electromagnetic wave and travels at a speed of 3.00 x 10^8 m/s. The human eye is most sensitive to yellow-green light, which has a wavelength of 5.45 x 10^-7m. How you find out the frequency of this light?
