Acurrent carrying wire (with current i) travels to the right. a loop of length a and width b (a> b) is at a distance r above the wire. the sides of length a are parralell to the wire. two resistors (r1, r2) are placed on each side of length b. a conducting rod is pulled to the left at constant speed v along the sides of length a, perpendicular to the wire. what are the currents going through r1 and r2?

Which of the following changes will result in a stronger electromagnet? a. using fewer coils of wire b. using a higher voltage c. using a shorter nail d. using a longer wire

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?
