A 40 g block of ice is cooled to -65°C. It is added to 569 g of water in an 69 g copper calorimeter at a temperature of 28°C. Find the final temperature. The specific heat of copper is 387 J/kg °C and of ice is 2090 J/kg °C. The latent heat of fusion of water is 3.33 x 105 J/kg and its specific heat is 4186 J/kg °C. Answer in units of °C.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
