Question

(1).The resistance of wire is giving by the relation Rt=Ro(1 alpha t Bt^2)
T is the temperature
alpha & Bt^2(beta) are constant
R=Resistance of the wire in ohms
Assuming the resistance of plantimum wire at 0°c,100°c,444.6°c and found to be 4.5,6.5 and 16.5 ohms respectively,Find the value of alpha & beta?
