An extension cord made of two wires of diameter 0.129 cm (no. 16 copper wire) and of length 1.8 m (6 ft) is connected to an electric heater which draws 17.0 a on a 120-v line. how much power is dissipated in the cord? express your answer using two significant figures.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
