A cylinder containing an ideal gas has a volume of 2.0m3 and a pressure of 1.0*105 Pa at a tempof 300 K. The cylinder is placed against a metal block thatis maintained at 900 K and the gas expands as the pressure remainsconstant until the temp of the gas reaches 900K. The changein internal energy of the gas is +6.0*105 J. How much heat did the gas absorb?
Photorefractive keratectomy (PRK) is a laser-based surgery process that corrects near- and farsightedness by removing part of the lens of the eye to change its curvature and hence focal length. What is the energy of a single photon
The first player has an acceleration whose magnitude is 0.5 m/s^2 and the second player's has an acceleration of 0.3 m/s^2. Explain by how much time passes before hey collide?
A mass-spring system oscillates on a horizontal frictionless surface with an amplitude of 3.02 cm. Determine the maximum speed of the mass
The coefficients of static and kinetic friction between a 67 kg box and a horizontal surface are 0.56 and 0.32, respectively. Illustrate what is the acceleration of the object if a 335 N horizontal force is applied to the box?
Two people with a combined mass of 120 kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 7.44 cm. Find the total load supported by the springs
Two cylindrical glass beads each of mass m = 32 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3 cm. The coefficient of static friction between the beads and the surface is μs = 0.3. The beads are the..
