Q. Two radio antennas are separated by 1.20 m. Both broadcast identical 750 MHz waves. If you walk around the antennas in a circle of radius 20.0 m, how many maxima will you detect?

Q. A 12.0 kg box resting on a horizontal, frictionless surface is attached to a 5.00 kg weight by a thin, light wire that passes over a frictionless pulley. The pulley has the shape of a uniform solid disk of mass 1.50 kg and diameter 0.600 m

a). After the system is released, find the horizontal tension in the wire.

b). After the system is released, find the vertical tension in the wire.

c). After the system is released, find magnitude of the horizontal and vertical components of the force that the axle exerts on the pulley.
