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.
A water pipe decreases in diameter from 16 cm to 8 cm. In the wider section the average velocity is 30.0cm/s. calculate the average velocity in the narrow section
A small statue is recovered in an archaeological dig. Its weight is measured to be 6.8 lb and its volume 0.09 ft3. What is the statue's weight density
A freezer has a coefficient of performance of 6.30. The freezer is advertised as using 430 kW-h/y, On average, how much energy does the freezer use in a single day
If a index card is 3inx5in and another is 5in x7in find the conversion factor by dividing the value in cm/in. Calculate the area of both index cards
a rigid tank of volume 0.5 m3 is initially evacuated. a hole develops in the wall and the air from the surroundings at
In a mass spectrometer, a singly charged ion having a particular velocity is selected by using a magnetic field of 0.1 T perpendicular to an electric field of 8.00 102 V/m. What is the mass of the ion
A soccer playrer kicks a 0.5kg ball from rest to a speed of 9m/s during a 0.15s contact between his foot and the ball. What is the average force applied by the players foot during the kick
A cockroach of mass m lies on the rim of a uniform disk of mass 7.00 m that can rotate freely about its center like the merry-go-round. At first the cockroach and disk rotate together with an angular velocity of 0.220 rad/s. Then the cockroach walks ..
When only a resistor is connected across the terminals of an ac generator (117 V) that has a fixed frequency, there is a current of 0.490 A in the resistor. calculate the impedance of the series combination
A space vehicle is coasting at a constant velocity of 15.1 m/s in the +y direction relative to a space station. find the direction of the vehicle's velocity relative to the space station
The former move along the surface of the earth much like the ripples in the surface of a pond, while the other type propagate through the whole earth forming a hemisphere around the point of origin of the quark assuming that it occurred close to t..
