Question

A 19 m long piece of wire of density 8.34 g/m3
has a diameter of 12.593 mm. The resistiv-
ity of the wire is 1.7e-8(ohm)(m) at 20 degrees celsius.
The temperature coefficient for the wire is
0.0038(degrees celsius)^-1.
Calculate the resistance of the wire at 20degrees Celsius.
Answer in units of ­.
(part 2 of 2) 10 points
Calculate the difference in the resistance of
the wire between 35degrees Celsius and 68degrees Celsius.
Answer in units of ­.

Answer 1

hi im the one who posted this question, i just wana say that the units of the answer in part 2 should be in ohms.
