Calculate the first five energy levels for CO (C=12,O=16) molecule with bond length of 112.8.
assume it rotates freely in the gas phase
assume it is absorbed on a solid surface (A catalytic converter) and moves freely only in 2 dementions
Galaxy A is moving away from us with a speed of 0.75c relative to the earth. Galaxy B is moving away from us in the opposite direction with a relative speed of 0.55c. Assume that the earth and the galaxies are moving at constant velocities, so they a..
Explain how much waork has been done against gravity when the crate is raised a vertical distance of 2.19 m? The coefficient of friction is 0.316.
The moon orbits the earth at a distance of 3.85 x 10^8 m.Assume that this distance is between the centers of the earth andthe moon and that the mass of the earth is 5.98 x 10^24 kg. Find the period (in days) for the moon’s motion around the earth.
In 1926, Albert Michelson measured the speed of light with a technique similar to that used by Fizeau. Find the required angular speed
A stone is thrown outward from the top of a 59.4m high cliff with an upward velocity component of 19.5 m/s. How long is the stone in the air
18 g of helium gas are placed in a cylinder with a movable piston. The gas is compressed very slowly from a state of ( p1 = 5.5atm, v1 = 32.7 × 10^3 m3) to a state of (p2 = 17atm, v2 = 11 × 10^3 m3 )
When yellow sodium light, ?=589nm, falls on a diffraction grating, its first-order peak on a screen 55.0cm away falls 3.29cm from the central peak. What is the wavelength of the new source
500 grams of water initially at 3.00 c and a 10.0 gram ice cube at 0.00c are placed together in an insulated styrofoam cup of negligible heat capacity. find the final temperature of the contents of the cup
A toy cannon uses a spring to project a 5.28 g soft rubber ball. The spring is originally compressed by 5.06 cm and has a force constant of 8.08 N/m. At what point does the ball have maximum speed
You are constructing a fiber optic cable. You wish to surround the core of the cable with a cladding material such that the critical angle to go from the core to the cladding is 73.0°
A stationary observer hears 597.6 Hz change to 447.8 Hz as a source of constant frequency passes at constant speed. find the source's speed and frequency
