1. A container with volume 1.68L is initially evacuated. Then it is filled with 0.240g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy.
a) If the root-mean-square speed of the gas molecules is 167m/s , what is the pressure of the gas?
2. Smoke particles in the air typically have masses of the order of 10^-16 kg. The Brownian motion (rapid, irregular movement) of these particles, resulting from collisions with air molecules, can be observed with a microscope.
a) Find the root-mean-square speed of Brownian motion for a particle with a mass of 3.00 x 10^-16kg in air at 300K.
A proton is located at the origin, and a second proton is located on the x-axis at x = 5.10 fm (1 fm = 10-15 m). If the two protons are released from rest and the alpha particle remains fixed, calculate the speed of the protons at infinity
A 0.50-?F and a 1.4-?F capacitor (C1 and C2, respectively) are connected in series to a 14-V battery. Calculate the charge on each capasitor assuming the two capacitors are in parallel
The proton is replaced with He2+ ion now at a distance of 3 cm from the bead. What is the magnitude of the force experienced by the helium ion
An airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 15 degrees south of east. What is the airplane's speed relative to the air mass
Since you are pulling up a little on the crate, the floor doesn't have to support as much weight. When you are pulling up on the rope as described above, what is the upward force that the floor exerts on the crate.
Laser light is shown through a diffraction grating with a line density of 880 lines per mm. What is the wavelength of the laser
Imagine that we connect a formula36.mml lightbulb and an formula37.mml lightbulb in parallel and connect the set to a 19-V battery
An air-track glider attached to a spring oscillates between the 8.00 mark and the 69.0 mark on the track. The glider completes 10.0 oscillations in 40.0 .
A pair of in-phase stereo speakers is placed side by side, 2m apart. You stand directly in front of one of the speakers, 5m from the speaker. What do you hear.
A research-level Van de Graaff generator has a 1.9-m-diameter metal sphere with a charge of 4.9 mC on it, What is the potential near its surface in MV
Smaller mammals use proportionately more energy than larger mammals; that is, it takes more energy per gram to power a mouse than a human. A typical mouse has a mass of 20 g and, at rest, needs to consume 3.0 Cal each day for basic body processes.
