The frequency band 870 - 890 MHz is used for analog (FM) cellular telephone systems. A base station transmits a signal with a power of 1 watt to an antenna
At t = 0, what is the torque acting on the wheel about the pivot? (Express your answer in terms of x,y and z components).
When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage.
A particle of mass m is attached to the end of a light string of length l. The other end of the string is passed through a small hole.
