Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.23 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 460 m/s. Assume that the collisions of the particle with the walls are elastic.
(a) Find the mass density inside the box.
(b) Find the average pressure on the walls perpendicular to the particle's path.
(c) Find the average pressure on the other walls.
(d) Find the temperature inside the box.

Here on Earth you hang a mass from a vertical spring and start it oscillating with amplitude 1.9 cm. How long does it take for the mass to make one round trip
A car is traveling 72.0 km/h when the driver applies the brakes. If if car slows down uniformly with an acceleration of -4.5 m/s2, how far does the car travel before coming to rest.
The resolving power of a microscope depends on the wavelength used. If you wanted to "see" an atom, a wavelength of approximately 1 × 10-11 m would be required.
