Answer my physics question plz.
A copper wire has a resistance of 50 ohms at 25°C (room temperature). The temperature coefficient of resistance for copper is approximately 0.0039 per °C.
Calculate the new resistance of the wire when it is heated to 100°C.

(Such a rod may be used to make nuclear- particle detectors, for example.)arrow_forwardExplain why R=R0(1 + a?T) for the temperature variation of the resistance R of an object is not as accurate as P=P0(1 + a?T) which gives the temperature variation of resistivity P.arrow_forwardReview. When a straight wire is warmed, its resistance is given by R = R0,[1 + a(T T0)] according to Equation 27.20, where a is the temperature coefficient of resistivity. This expression needs to be modified if we include the change in dimensions of the wire due to thermal expansion. For a copper wire of radius 0.100 0 mm and length 2.000 m, find its resistance at 100.0C, including the effects of both thermal expansion and temperature variation of resistivity. Assume the coefficients are known to four significant figures.arrow_forward
