A construction worker slides a 40kg block with a force of 210N [W] along a rough floor for 7.5m [W] and then picks up the block and places it on a wall 185cm high. Determine the energy needed to accomplish this task.
State how a potential could be induced, using a bar magnet, in the coil shown below that would have current flow through the ammeter from left to right. Explain why the potential would flow as stated.
