Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.05 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 340 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.
In a simple atom, the electrons making transitions between outermost energy levels and the innermost energy levels give rise to photons with the reddest colours.

A uniform magnetic field of magnitude B= 1.2 teslas is directed toward the bottom of the page in the -y direction as shown above. At time t=0, a proton p in field is moving in the plane of the page with a speed v0= 4 x 10^7 meters per second in a ..
A playground merry-go-round of radius R = 2 m has a moment of inertia I = 275 kg•m2 and is rotating at 14 rev/min about a frictionless vertical axle.
A galvanometer with a coil resistance of 14.1 is used with a shunt resistor to make a nondigital ammeter that has an equivalent resistance of 0.755. determine the full-scale current of the galvanometer
Calculate the angular velocity the flywheel must have to contain enough energy to take the bus from rest to a speed of 27.0 m/s, assuming 83.0% of the rotational kinetic energy can be transformed into translational energy
Since the vehicles stick together after the collision and take the direction of the large truck (greater momentum), I guessed that the small car would have a greater change in kinetic energy.
