An AC generator consists of 8 turns of wire in a loop or coil, the cross-sectional area of the loop is A=0.09 m2, with a total resistance of 12Ω. The loop is rotating in a magnetic field B=0.5T at a constant rate of 60Hz.
A) Discover the maximum EMF and current induced in the coil;
B) Inscribe the equations for the time variation of the induced EMF and current.
A 120-V(RMS) space heater has two power settings: 750 W and 1500 W. What is the resistance of the lower power setting
On a frictionless horizontal air table, puck A (with mass 0.253kg ) is moving toward puck B (with mass 0.365kg), which is initially at rest. After the collision, puck A has velocity 0.115m/s to the left, and puck B has velocity 0.655m/s to the right...
