A device has a 100 g wooden shuttle that is pulled horizontally along a square frictionless wooden rail by an elastic band. The shuttle is released when the elastic band has 6.4 N tension at a 35° angle. What is the magnitude of the initial acceleration of the shuttle.
A ray of light traveling through air encounters a 1.7cm -thick sheet of glass at a 42? angle of incidence. Assume n = 1.5. How far does the light ray travel inside the glass
a freezer compartment consists of a cubical cavity that is 2 m on a side. assume the bottom to be perfectly insulated.
In a Rutherford scattering experiment, an ?-particle (charge = +2e) heads directly toward a silver nucleus (charge = +47 e). The ?-particle had a kinetic energy of 4.7 MeV when very far (r ) from the nucleus. Assuming the silver nucleus to be fixed i..
