You are given a straight piece of conductor that is 4.3 cm long and moves in a region of uniform magnetic field of 1.7 t along the z-direction. if the conductor is oriented along the x-axis and moves in the y-direction with a velocity of 5.0 m/s, find the magnitude of induced voltage that will be produced between the ends of this moving conductor.

Abaseball has a mass of 0.145 kg and approaches a bat at 40.0 m/s. after it is hit, the ball leaves the bat at 50.0 m/s directly back. find the impulse of the bat on the ball. 7.25 kg*m/s 13.1 kg*m/s 5.80 kg*m/s 1.45 kg*m/s

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
