1.You have two wires connected end to end. Wire 1 is copper and wire 2 is made using a special carbon conductor. Wire 1 has a resistance of 0.215 ohms/ft and is 500 ft long. Wire 2 has a resistance of 0.141 ohms/ft and is 700 ft long. Both of these resistances are measured at 20 degrees Celsius. If the ambient temperature is 99 degrees Farenheit, what is the change in the wire's total resistance?

2.A Bonda portable generator is powering a small travelling fridge (120V) in your RV and consumes 125 watts. The efficiency of the generator's gas motor is 23% and the electrical portion (power head) is more efficient at 91%. If white gas weighs 6.073 lb/gallon, and has a caloric value of 20,400 BTU/lb, how long will the generator run on a tankful of fuel (2.20 gallons). (You will need to know that 1 BTU = 1055 J)
