Q. An ideal monatomic gas initially has a temperature of 311 K and a pressure of 7.57 atm. It is to expand from volume 571 cm3 to volume 1390 cm3. If the expansion is isothermal, what are (a) the final pressure (in atm) and (b) the work done by the gas? If, instead, the expansion is adiabatic, what are (c) the final pressure (in atm) and (d) the work done by the gas
Q. A 0.30 kg softball has a velocity of 15 m/s at an angle of 35 degrees below the horizontal just before making contact with the boat. What is the magnitude of the change in momentum of the ball while in contact with the bat if the ball leaves with a velocity of (a) 20 m/s vertically downward, and (b) 20 m/s horizontally back toward the pitcher?
And if the plane could fly without this pilot, how much force would the plane require to maintain the equal acceleration?
A thin, light wire is wrapped around the rim of a wheel. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.28. An object of mass 4.0 is suspend..
A rabbit runs in the straight line with a velocity of +1.6 m/s for a period of time, rests for 12 s, and then runs again along the equivalent line at +0.52 m/s for an unidentified amount of time. The rabbit travels the total distance of 1224 m, and i..
A chair of weight 74.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 47.0 N directed at an angle of 41.0^circ below the horizontal and the chair slides along floor.
A screen is placed 51.0 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 2.80 mm, what is the width of slit.
While john is travelling along an interstate highway, he notices a 160 mile marker as he passes through town. Later John passes another mile marker, 119.
A screen is placed 1.30 {rm m} behind a single slit. The central maximum in the resulting diffraction pattern on the screen is 1.70 {rm cm} wide-that is, two first-order diffraction minima are separated by 1.70 {rm cm}.
A 13 turn circular loop of wire has a diameter of 0.66m. The plane of the circular loop creates an angle of 63 to the Earth's magnetic field. In 0.15s the coil is flipped at a location where the magnitude of the Earth's magnetic field is 34 μT.

The coefficient of kinetic friction is 0.50. A horizontal force of magnitude 87 N begins to pull directly on the block. In unit-vector notation, what are the resulting accelerations of (a) block and (b) slab.
A luge and its rider, with a total mass of 104 kg, emerges from a downhill track onto a horizontal straight track with the initial speed of 53 m/s. suppose they stop with the constant deceleration of 2.30 m/s2.
