An ideal monatomic gas at temperature T is held in a container. If the gas is compressed isothermally, that is at constant temperature, from a volume of Vi to Vf,
a) What is the change in the (internal) energy of the gas?
b) How much work has been done on the gas?
c) Has heat been transferred into or out of the gas during the process? If so, how much?
d) Show that the 1st law of thermodynamics is satisfied.
Consider a collision between an x-ray photon of initial energy59.0 keV and an electron at rest, What is the energy of the back-scattered photon
Consider the case when light passes from one medium into another medium that has a lower index of refraction, for instance, from glass to water. Is there an angle of incidence for which the refracted angle is 90 degrees? If there is, derive an exp..
a hot-air balloon is ascending at the rate of 11 ms and is 59 m above the ground when a package is dropped over the
A rod flies with constant velocity past a mark which is stationary in the K frame. In the K frame, it takes the rod Deltat = 20 ns to fly pass the mark. In the K' frame fixed to the rod, the mark moves past the rod in Deltat' = 25 ns. Find (a) the ve..

A car is traveling on a straight road and always heads in the same direction. The car starts from rest, undergoes constant acceleration for (tau) seconds to reach a velocity of 45 m/s, and travels afterward at this constant velocity of 45 m/s.
My 17 kilogram son goes down a straight slide that makes a 40 degree angle with the horizontal. Obtain what the coefficient of kinetic friction of the slide
Several bacteria are propelled by biological motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocity has a radius of 1.22*10-8 m, and a tangential speed at the rim of 2.41*10-5 m/s.
