1. What is the relationship between the temperature of a gas and its distribution of kinetic energies? Is it possible to have particles with kinetic energies many multiples of the most common value?
2. What is the relationship between the speed distribution of a gas and the mass of the particles? How does this help to explain the relative ease with which hydrogen escapes from its containers?
At a recent rock concert, a dB meter registered 114 dB when placed 1.00 m in front of a loudspeaker on the stage. What was the power output of the speaker, assuming a hemispherical radiation of the sound and neglecting absorption in the air?
A laser beam of power 4.40 W and diameter 2.70 mm is directed upward at one circular face of a perfectly reflecting cylinder, which is made to "hover" by the beam's radiation pressure
A two stage rocket with a total mass of 925kg is traveling at a speed of 6.6 10^3 m/s away from the earth . A predesigned explosion separates into two sections of equal mass that move with a speed of 2800m/s relative to each other along the origin..
A grating that has 3600 slits per cm produces a third-order fringe at a 22o angle. What wavelength of light is being used? Express your answer to two significant figures and include the appropriate units.
In compressing the spring in a toy dart gun, 4 Joule of work is done. Calculate the dart kinetic energy as it leaves the gun
Ultrasound is the name given to frequencies above the human range of hearing, which is about 20000 Hz. Waves above this frequency, can be used to penetrate the body and to produce images with reflecting from surfaces.
