A gas is orignally contained within a container of volume 100m^3 and is held at a pressure of 1 atmosphere and temperature of 15C. Due to equipment failure, the temperature rises to 66C, but the safety systems do not allow the pressure to exceed 1.1 atmospheres. during the repair, it is noticed that the safety systemes have vented gas in to the air to maintain the presure at a safe level.
a. How many moles of gas were orignally contained?
b. how much gas has been lost into the atmophere during this process.
Write down your expression in terms of the dipole moment. Express your reply in terms of, and appropriate constants.
An explorer is caught in a whiteout (in which the snowfall is so thick that the ground cannot be distinguished from the sky) while returning to base camp.
A 4.9 cm tall object is placed 25 cm in front of a spherical mirror. It is desired to produce a virtual image that is upright and 3.9 cm tall. Where is the image located? What is the focal length of the mirror?
A father and a daughter balance a teeter-totter to illustrate the principle of the lever. If the father whose weight is 150 N is 8 m from one end, how far away on the opposite side of the fulcrum should the 50-N daughter stand to balance the teeter-t..
moves through its horizontal position at (B) and up to (C) where it stops with 2 = 109.0o, and then falls back down. Friction at the pivot is negligible. Compute the speed of the CM at (B).
A simple generator has a 620-loop square coil 21cm on a side. How fast must it turn in the 0.690 T field to produce a 140 V peak output.
A novice golfer on the green takes three strokes to sink the ball. The successive displacements of the ball are 4.00 m to the north, 2.00 m northeast, and 0.90 m at 35.0° west of south. begining at the same initial point, an expert golfer could ma..
At rest, the car's horn sounds at a frequency of 455 Hz. The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-third the car's speed hears a frequency of 427 Hz. What is speed of the car.
A 2.65 block is pushed 1.69m up a vertical wall with a constant speed by a constant force of magnitude F applied at angle 55.4 degrees with the horizontal. g= 9.8 m/s2. If the coefficient of kinetic friction between the block & wall is 0.54, Calcu..
An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 21.0 days on average to complete one nearly circular revolution around the unnamed planet.
Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. Illustrate what is the change in the car's kinetic energy, ΔKE = KEf - KE0, fro..
