1. Consider a wire with resistivity of (1.20+A)x10-7 Ω m, a diameter of (1.50+B) mm, and a length of (15.0+C) m. Determine the resistance of the wire in ohms (Ω). Round your answer to three significant figures.
A = 8 B = 1 C = 12
2. An (11.4 + A) ohm device is connected to a 115 V outlet. If the cost of the electrical energy is $0.16/kWh, determine the cost of running this device for (36.0 + B) hours. Round your answer in dollars ($) with 2 decimal places.
A = 18 B = 12
