... Law of Conservation of Energy and Efficiency 1. Kate plugs in her hair dryer. The device uses 12,000 J of energy. 8,500J is converted to motion to move the inner fan, 500J is converted to sound, and 1,500 is converted to thermal energy. Does this support the law of conservation of energy? Explain. ...

... the energy given out by food. It is difficult to measure the energy of food directly. So we have to measure it indirectly. We can measure the energy by burning it in calorimeter, since the (heat) energy given out in the burning process is nearly is the same when it is digested and absorb inside body ...

... Problem 20. In 1911, Ernest Rutherford and his assistants Hans Geiger and Ernest Mardsen conducted an experiment in which they scattered alpha particles from thin sheets of gold. An alpha particle, having a charge of qα = +2e and a mass of m = 6.64 · 10−27 kg is a product of certain radioactive deca ...

... At the points, where E U (x) , the kinetic energy is zero. Regions where the kinetic energy is negative, are called the classically forbidden regions, which the body can never reach if subject to the laws of classical mechanics. In quantum mechanics, there is a very small probability that the body ...
