Consider 10 moles of nitrogen within a cylinder with.a cross sectional area o f 1 m^2. Assume that the cover ("cap") ofthe cylinder, is a disk which can slide frictionlessly within the cylinder. Assume that the cap makes a "leak-proof' fit so that 10 moles of nitrogen always exist within the cylinder, independent of the cap height. The gas in the cylinder has pressure 120xl0^3 Pa.
An additional 2000-kg mass is placed on the cap, which causes the cylinder to finally contract to a final equilibrium height of 15 cm. Compute the new temperature of the gas contained within the shorter cylinder. Assume the cylinder is in contract with an appropriate thermal reservoir, i.e., that heat can flow in or out of the gas. Assume g = 9.8 m/s^2.
Calculate the acceleration of a 1400-kg car that stops from 34km/h "on a dime" (on a distance of1.7 cm). Determine the acceleration of the car
An automobile accident investigator needs to determine the initial westerly velocity of a Jeep (m=1720 kg) that may have been speeding before colliding head-on with a Volkswagen (m=1510 kg) that was moving with a velocity of 75.7 km/h east. Find t..
A 2.26 kg block is on a plane inclined at 22.4 degrees with respect to the horizontal. How many forces are acting on the block
A football is kicked off at a speed of 24 m/s at 30 degree about the horizontal and lands on the field. What is the horizontal distance from the starting point
Determine the required angular speed of an ultracentrifuge for the radial acceleration of a point 2.12 centimeter from the axis to equal 425,000 gram
If the balls are far enough apart to behave more or less like equal point charges, then Fcoul should be given by Fcoul = kq2/R2. Write an equation that can be used to determine the amount of charge, q, on each ball as a function of m, R, and L as ..
You heat a 545 cm^3 sample of a substance from 121 celcius to 285 celcius and find that its volume increases by 2.29 cm^3. obtain the coefficient of volume expansion of this substance
A 2.0 kg mass attached to a light spring with a spring constant of 46 N/m oscillates on a frictionless horizontal surface. Find the maximum speed of the mass in its oscillation
A sled of mass m is given a kick on a frozen pond. The kick imparts to it an initial speed of vi = 2.50 m/s. Use energy considerations to find the distance the sled moves before it stops
A small spherical insulator of mass 4.95 × 10-2 kg and charge +0.600 C is hung with a thin wire of negligible mass. A charge of -0.900 C is held 0.150 m away from the sphere and directly to the right of it, so the wire makes an angle by the vertical ..
