1. At 60.0 degree C, a certain material has a resistance that is twice as large as its resistance at 20.0 degree C.

a. What Is the thermal coefficient of resistivity for this material?

b. A resistor made of this material has a length of 2.00 cm and a radius of 5.00 mm. If its resistance is 80.0 k Ohm, what is the resistivity for this resistor?

c. The resistor is placed in a circuit such that 6.00 mA of current flow through it. If the resistor has an electron density of 2.39 times 1023 electrons/m3, what is the drift speed of the electrons?

d. What is the potential difference across the resistor while in this circuit?
