Which of these is an experiment generally regarded as being first carried out by james joule?
observing that objects increase in temperature when heated with fire
showing that friction slows down the motion of objects
measuring the temperature increase of water from doing work stirring it
testing the mechanical advantage of pulleys
what did joule's experiment directly show?
the temperature of water increases from the addition of heat.
heat is a form of energy.
heat can be neither created nor destroyed.
electromagnetic radiation has energy

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
