Which energy transformation occurs in the core of a nuclear reactor?
a. nuclear energy to mechanical energy
b. nuclear energy to thermal energy
c. thermal energy to nuclear energy
d. mechanical energy to nuclear energy

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?
