A 2.40cm × 2.40cm square loop of wire with resistance 1.10×10?2? has one edge parallel to a long straight wire. The near edge of the loop is 1.10cm from the wire. The current in the wire is increasing at the rate of 120A/s. What is the current in the loop?
(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 11.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) Imagine adding electrons to the pin until the negative charge ha..
