A solenoid used to produce magnetic fields for research purposes is 2.1 m long, with an inner radius of 28 cm and 1300 turns of wire. When running, the solenoid produced a field of 1.3 T in the center. Given this, how large a current does it carry?

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
