In the park, a mom pushes tangentially on a hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 25 rpm in 11.0 second. Suppose the merry-go-round is a uniform disk of radius 2.5 meter and has a mass of 800 kilogram, and two children (each with a mass of 20 kilogram) sit opposite each other on the edge.
Find the torque required to produce the acceleration, ignore frictional torque. m•N
Determine what force is required at the edge?
N
Aluminum has a density of 2.7 103 kg/m3 and a molar mass of 27 g/mol. The Hall coefficient of aluminum is R = -3.0 10-11 m3/C. What is the number of conduction electrons per aluminum atom?

A moon orbits a planet because of the gravitational force between them. Similarly, each body also experiences a tidal force due to gravity. Consider how the magnitude of the tidal force changes as distance between a planet and moon varies.
Standing at a crosswalk, you hear a frequency of 590 Hz from the siren of an approaching ambulance. Determine the ambulance's speed from these observations
