14. A thermistors resistance varies with temperature as:
R=R0eBT where R is in ohms Ω, T is in kelvins, and R0 and B are
constants. If R=8991.9 Ω at the ice point and R=358 Ω at the steam
point, Ts=373.15K.
Determine B.

The resistance R of a wire varies directly with the length L of the wire and inversely with the square of its radius r. A wire with a length of 350 cm and a radius of 0.4 cm has a resistance of 16 ohms. Determine the resistance of a 500 cm piece of similar wire with a radius of 0.35 cm. Round your final answer to four decimal places and be sure to include units.
