A circular coil that has =300 turns and a radius of =12.0 cm lies in a magnetic field that has a magnitude of 0=0.0670 T directed perpendicular to the plane of the coil. What is the magnitude of the magnetic flux Φ through the coil?

Φ=

T⋅m2
The magnetic field through the coil is increased steadily to 0.170 T over a time interval of 0.350 s.

What is the magnitude || of the emf induced in the coil during the time interval?

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
