Q1. The density of free electrons in gold is 5.90 x 10^28 m-3. The resistivity of gold is 2.44 x 10-8 at a temperature of and the temperature coefficient of resistivity is 0.004 ()-1. A gold wire, 1.30mm in diameter and 27cm long, carries a current of 270mA. The electric field in the wire is closest to?
Q2. Some good estimates about the human body can be made if it is assumed that we are made mostly of water. The mass of a water molecule is 2.99 x10-26 kg. If the mass of a person is 62.0 kg, estimate the number of water molecules in that person.
