The rms speed of the molecules in 1.5g of hydrogen gas is 1800m/s . A:What is the total translational kinetic energy of the gas molecules? B:What is the thermal energy of the gas? C: 300 J of work are done to compress the gas while, in the same process, 1400J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules?

Vector has a magnitude of 7.20 units and makes an angle of 39.5° counter-clockwise from positive x-axis. Vector has a magnitude of 8.00 units and is directed along the negative x-axis.
The magnitude of the electrostatic force between two identical ions that are separated by a distance of 0.90 nmis 4.103×10-8 N, How many electrons are missing from (or have been added to) each ion
A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one o..
A bicycle wheel of mass M (assumed to be concentrated at its rim) and radius R is mounted horizontally so it may turn without friction on a vertical axle. A dart of mass mo is thrown with velocity vo above and sticks in the tire.
what is the equivalent resistance between points A and B?
A concrete highway curve of radius 60 m is banked at a 13.0^circ angle. What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
Establish the initial volume of the gas . What is the magnitude of normal force that each brake pad applies to the rim.
