Q. An engine goes through the following cycle with 2.20 sample of a diatomic gas. I. an isothermas expansion from point a to point b. II. a constant pressure compression from point b to point c. III. An adiabatic compression from point c to point a. We are given point a has a temperature 421, and a volume 2.00×10-3 .What is the pressure in Pascals at point a?
Part BWhat is the pressure in Pascals at point b if volume of point b is 0.210 ?
Part Cwhat is the volume at point c?
Part Dwhat is the temperature at point c?
Part Ewhat is the change in internal energy for process II?
Part Fwhat is the work done in process II?
Part Gwhat is the heat transfer in process II?
A rock of mass 32kg accidentally breaks loose from the edge of a cliff and falls straight down. The magnitude of the air resistance that opposes its downward motion is 274N. What is the magnitude of the acceleration of the rock.
A bumper car with mass m1 = 129 kg is moving to the right with a velocity of v1 = 4.50 m/s. A second bumper car with mass m2 = 86.0 kg is moving to the left with a velocity of v2 = -3.6 m/s. The two cars have an elastic collision. Suppose the surface..
find the potential energy at each location below. How far from the point of the drop will the rock hit the ground.

A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6. What is the car's minimum breaking distance?
A 11 g bullet is fired horizontally into a 109 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 142 N/m. The bullet becomes embedded in the block.
A hotel elevator ascends 160m with a maximum speed of 4.20 m/s. Its acceleration and deceleration both have a magnitude of 1.0 m/s2. How long does it take to make the complete trip from bottom to top.
The mass of the Moon is 7.35 × 10^22 kg, whereas that of Earth is 5.98 × 10^24 kg. The average distance from the center of the Moon to the center of Earth is 384,400 km.
A small glass bead has been charged to + 10nC. A metal ball bearing 1.90cm above the bead feels a 1.20×10-2 N downward electric force. What is the charge on ball bearing.
