The loop in the figure is being pulled with a speed 80 m/s into a uniform magnetic field of magnitude B = 0.90 T
The loop in the figure is being pulled with a speed 80 m/s into a uniform magnetic field of magnitude B = 0.90 T that is directed into the page. The resistance of the loop is 0.10 Ω and its length is l = 4.00 cm. (Figure 1) What is the direction of the induced current in the loop? Part What is the induced current after the entire loop has entered the uniform magnetic field?

A glider with mass m = 0.200 kg sits on a frictionless horizontal air track, connected to a spring with force constant k = 5.20 N/m . You pull on the glider, stretching the spring 0.130 m , and then release it with no initial velocity. The glider begins to move back toward its equilibrium position ( x=0 ). Part A What is the speed of the glider when it returns to x=0 ? Part B What must the initial...

A horizontal spring with force constant k = 700 N/m is attached to a wall at one end and to a block of mass m = 2.30 kg at the other end that rests on a horizontal surface. The block is released from rest from a position 3.40 cm beyond the spring's equilibrium position. (a) If the surface is frictionless, what is the speed of the block as it passes through the equilibrium position? m/s (b) If the surface is...
