If you use this disk as a pendulum bob, what is t(d), the period of the pendulum, if the axis is a distance d from the center of mass of the disk? express the period of the pendulum in terms of given variables.

State the right hand rule of the direction of magnetic field in a conductor carrying current

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?
