Generations (Calculate Maximum EMF in Coil)

A 95 turn square wire coil of area 0.040 m2 rotates about a vertical axis at 1730 rpm, as indicated in Figure P20.30 {attached}. The horizontal component of the Earth's magnetic field at the location of the loop is 2.0 10-5 T. Calculate the maximum emf induced in the coil by the Earth's field. (answer in V)

Problem 6.21

You are asked to consult for the city's research hospital, where a group of doctors is investigating the bombardment of cancer tumors with high-energy ions. The ions are fired directly toward the center of the tumor at speeds of 6.00E6 m/s. To cover the entire tumor area, the ions are deflected sideways by passing them between t ...continues

Circular Launch (Centripetal Acceleration)

A ball is launched up a semicircular chute in such a way that at the top of the chute, just before it goes into free fall, the ball has a centripetal acceleration of magnitude 2g. A. How far from the bottom of the chute does the ball land? (Your answer for the distance the ball travels from the end of the chute should contain ...continues

Problem 7.24

A 5.0-m-diameter merry-go-round is initially turning with a 4.0 s period. It slows down and stops in 20 s. a) Before slowing, what is the speed of a child on the rim? (in m/s) b) How many revolutions does the merry-go-round make as it stops?

Three-Block Inelastic Collision

A block of mass m1 moving with speed v1 undergoes a completely inelastic collision with a stationary block of mass m2. The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3, which is initially stationary. The three blocks then move, stu ...continues
