In general the quantization of transitional motion is insignificant for atoms because of their mass. However this depends on the dimensions of space to which they are confined. Zeolites are poruous alumnosilicates that can be described by a cube iwht an edge length of one nanometer. Calculate the energy of H2 molecule where nx = ny = nz - 10. By comparing this energy to kT with T = 300K, determine whether a classical or quantum mechanical description can be used.
q1. suppose a constant ratio of 13.60 counts per minute per gram of living matter. a sample of a petrified tree was
A container holds 2.0 mol of gas. The total average kinetic energy of the gas molecules in the container is equal to the kinematic energy of an 8.0 X 10^-3kg bullet with a speed of 770m/s
An AC generator is to have a maximum output of 346 V. Each coil has an area of 0.149 m2 and a resistance of 16.6 %u03A9, Find the maximum current induced in the coil
Water at a pressure of 3.2 atm at street level flows into an office building at a speed of 0.5 m/s through a pipe 5.6 cm in diameter. Calculate the water pressure in such a pipe on the top floor
The spheres are brought into contact and then separated to a distance of 2.40 cm. Determine the magnitude of the force that each sphere now experiences, and state whether the force is attractive or repulsive.
There are four charges, each with a magnitude of 1.9 µC. Two are positive and two arenegative. The charges are fixed to the corners of a 0.27 m square, one to a corner, in such a way thatthe net force on any charge is directed toward the center of..

q1. a 58.0-kg projectile is fired at an angle of 30.0deg above the horizontal with an initial speed of 1.26 102 ms from
Air (k = 1.4) flows isentropically through a converging-diverging nozzle from a large tank where it is maintained at 59F, 80 psia. Find the mach number and the velocity (ft/s) at the exit
A violin string has a length of 0.360 m and is tuned to concert G, with fG = 392 Hz. (a) How far from the end of the string must the violinist place her finger to play concert A, with fA = 440 Hz? cm from the bridge (b) If this position is to remain ..
A 0.19 kg meterstick has a 0.17 kg mass at its 40 cm mark and a 0.45 kg mass at the 85 cm mark. Where should the fulcrum be so the meterstick is balanced
