A student measures the length of a brass rod with a steel tape at 20.0°C. The reading is 95.00 cm. What will the tape indicate for the length of the rod when the rod and the tape are at each of the following temperatures?

a)-20°C

b)60°C

I will be happy to critique your work on this.

new reading= L+deltaL

DeltaL=L*coeffthermalexpansion*deltaTemp

question: do you multiply the coefficient for steel in the equation and the coefficient for brass in a separate equation and add them together to get the answer?
