A Gas of diatomic molecules is in equilibrium at a temperature of 340 K. Assuming that the rotational inertia of the molecule is 2.5 x 10-40 kg•m2, find what is the rms angular speed of the molecules? Determine the mean angular momentum of the molecules?
In reaching her destination, a backpacker walks with an average velocity of 1.19m/s, due west. This avg velocity results bc she hikes for 5.7 km with an avg velocity of 2.18 m/s due west, turns around, and hikes with an avg velocity of 0.511m/s du..
You are standing on the edge of a turntable with frictionless bearings. It is initially rotating when you catch a ball, which is moving in the same direction but faster than you are moving and ona line tangent to the edge of the turntable. Assume ..
In the Millikan oil-drop experiment, an atomizer (a sprayer with a fine nozzle) is used to introduce many tiny droplets of oil between two oppositely charged parallel metal plates.

a skateboarder starting from rest rolls down a 13.0 m ramp. when she arrives at the bottom of the ramp her speed is
A 27 pound meteorite struck a car, leaving a dent 26cm deep in the trunk. If the meteorite struck the car with a speed of 620m/s, what was the magnitude of its deceleration, assuming it to be constant.
Two traveling sinusoidal waves are described by: y1=(5.00m) sin[4.00x-1200t] and y2=(5.00m) cos[4.00x-1200t] Determine amplitude, wavelength, frequency and speed of the resultant wave.
The solar neutrino problem has been "solved" by discovering that neutrinos have mass and they oscillate. Therefore how accurate are now our predictions about the number and kinds of solar neutrinos that reach the earth?
A sledge loaded with bricks has a total mass of 17.5 kg and is pulled at constant speed by a rope inclined at 20.3° above the horizontal. How much work is done by the rope on the sledge
