You are looking down on a n = 24 turn coil in a magnetic field b = 1 t which points directly down into the screen. if the diameter of the coil d = 3.7 cm, and the field goes to zero in t = 0.08 seconds, what would be the magnitude of the voltage (in volts) and direction of the induced current? indicate the direction of the current by the sign in front of your voltage: counterclockwise is positive, clockwise is negative.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
