By observing that the centripetal acceleration of the moon around the earth is ac = 2.74 × 10-3 m/s2, what is the gravitatonal constant g, in cubic meters per kilogram per square second? assume the earth has a mass of me = 5.97 × 1024 kg, and the mean distance between the centers of the earth and moon is rm = 3.81 × 108 m.

Which describe reflection? check all that apply. light bounces off a boundary.

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
