Ask your teacher an electric utility company supplies a customer's house from the main power lines (120 v) with two copper wires, each of which is 34.0 m long and has a resistance of 0.109 ω per 300 m. (a) find the potential difference at the customer's house for a load current of 116 a.

iron would move it is magnetic there is a mag field around the current in the wire

no sign of dia of fuel cell

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
