Over a period of four minutes, a total of 49,570 J of heat energy are transferred to a 875 g copper kettle by an electric stove. The temperature of the kettle increases from 25.0 °C to 173
°C. Assuming no energy is lost to the surroundings, calculate the specific heat capacity of
copper in J/g °C.

Which type of stress results when two plates push against one another? a. compression b. tension c. force d. shear

Define a is a tiny pavket of energy
