Dr. Terror has developed a new alloy called Ultranomium. Hes testing a bar that is 1.25 m long and has a mass of 342 grams. Using a carbon-dioxide infrared laser, he carfully heats the bar from 23.6 °C to 288 °C.
A: If the bar absorbs 8.93 × 10^4 J of energy during the temperature change, what is the specific heat capacity (c) of the Ultranomum?
B: He notices that at this new temperature, the bar's length has increased by 1.422 × 10^-3 m. What is the coefficient of linear expansion (α) for the new alloy?
