Atoroid is constructed from insulated copper wire that has diameter 1mm. the cross-sectional diameter of the toroid is 1 cm. the radius of the toroid as measured to the center of its cross-section is 10.5 cm. the resistivity of copper is 1.7 x 10-6 ω-cm.
a) how many turns are there on this toroid?
b) calculate its self-inductance.
c) what is the energy stored in the toroid for an applied potential difference
of 0.1 v ?
d) what would be the value of a capacitor that would store the same energy if it was also charged to 0.1 v ?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
