Please answer the following two questions:

3) Two cylindrical copper wires with a radius of 39 cm are connected to a battery and then they are connected across an incandescent light bulb and the light bulb turns on and is some brightness. If you took the same battery and connected coppers two wires which were a factor of 6 times longer than the first two wires to the same lightbulb so that the lightbulb was the exact same brightness as the first wires (it's not dimmer or brighter), what must be the radius of the second wires in cm?

4) Electricity is actually a very cheap form of energy. Suppose the cost of energy is 17.5 cents/kwh. If all the electrical energy used in purchasing $1 of electricity were converted to potential energy of raising 30,000 kg truck, how high above the ground would the truck be raised in m?

A compound string is made by fusing together two wires of equal length and radius, but different materials: A and B. The mass density of material A is 9 times the mass density of material B. Under some unknown tension, the compound string is driven at increasing frequencies. At some unknown frequency, a standing wave is established with nodes at the ends of the compound string and at the interface between the two materials. Given that the tension is constant...
