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.
Air in a diesel engine cylinder is quickly compressed from an initial temperature of 20 °C, an initial pressure of 1 atm, find the final temperature and pressure
A cat is trying to jump onto a countertop that is 1m tall from 0.3m away. The cat's initial jump speed (magnitude of the total initial velocity) is 10m/s
What is the order of magnitude of the maximum displacement of a Cu atom at the Debye temperature? Campare this displacement with the interatomic distance.
Consider two dipoles, p1, oriented along z at the origin, and p2 oriented along x at a distance r in the x-y plane. Given that the torque on a dipole in a field E can be written N=p cross E, find the torque on each dipole about its centre.
A pilot wants to fly due north a distance of 125 km. The wind is blowing out of the west at a constant 35 km/h. If the plane travel at 175 km/h, how long would the trip take.
We have a hollow metallic sphere with charge -5.0 µC and radius 5.0 cm. What charge now rests on the outer surface of the sphere
A pacific north west home has a solar photovoltaic (PV) systemthat produces 10.45 MWh of usable electricity peryear. Their PV system is tied to the electrical grid, and all theenergy it produces is credited against their energy homeconsumption.
A worker pushed a 22 kg block 8.1 m along a level floor at constant speed with a force directed 39° below the horizontal. find the increase in thermal energy of the block-floor system
A parallel plate capacitor has a left plate with a positive charge of +Q and a right plate with a charge of -Q. The magnitude of the electric field between the plates is 100 V/m The plates each have an area of 2.0x10-3 m2 with a spacing of plate..
What is the kinetic energy
A spacecraft of 140 kg mass is in a circular orbit about the Earth at a height h = 3RE. What is the spacecraft's kinetic energy
