A beam of monochromatic light is incident on a single slit of width 0.620 mm. A diffraction pattern forms on a wall 1.35 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.08 mm. Calculate the wavelength of the light.
A small sphere with mass 2.60g hangs by a thread between two large parallel vertical plates 5.00cm apart. What potential difference between the plates
A 2.0kg solid cylinder (radius = 0.10m , length = 0.70m ) is released from rest at the top of a ramp and allowed to roll without slipping. When the cylinder reaches the bottom of the ramp, what is its total kinetic energy
Explain the difference between a fluorescence emission spectrum and a fluorescence excitation spectrum, What is the force constant for the CO bond
An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor would the amplitude of oscillation decrease after 10 cycles.

On a winter day heat leaks out of a house at the rate of 2.5x10^4 kcal/h. At what rate does this process produce entropy
Find the lower limit for the change in specific entropy of dry air at a given temperature and pressure which is allowed to expand freely into an insulated chamber to assume twice its original volume.
A piston-cylinder device initially contains 1 m of nitrogen gas at 400kpa and 27 c. Determine the final temperature of nitrogen
A tuning fork with a frequency if 536 Hz is placed near the top of a tube opened at one end and closed at the other end. The water level is lowered so that the length of the air column slowly increases from an initial value of 20.25cm. Determine the ..
