Suppose an ideal monatomic gas at an initial temperature of 475 K is compressed from 3.20 L to 2.15 L while its pressure remains constant at 1.01 105 Pa.
(a) Find the work done on the gas.
(b) Find the change in internal energy.
(c) Find the energy transferred by heat, Q.
David is driving a steady 25 m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.8 m/s^2 at the instant when David passes.
A certain protein molecule is hydrolyzed by an enzyme. How would you define this statement in your own words to someone who is not familiar with chemical terminology.
In the typical X-ray lamp. The electrons are accelearated in the potential difference of 10000V before hitting the water cooled electrode. Find the shortest wavelength of X-rays produced in this lamp.
You push on the chair with a force of = 42.0 directed at an angle of 34.0 below the horizontal and the chair slides along the floorcalculate, Illustrate what is the magnitude of the normal force that the floor exerts on the chair.
How fast would it be moving after it had fallen a distance of 0.010-m? (Assume that the gravitational force is constant over the distance of the fall, and that the star is not rotating.)
Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. Determine the current in the rods
What is the phase dierence between wavefronts originating from the two slits, at a point on the screen located +Π/10m from the zero'th order?
A thin rod of length 0.75 m and mass 0.35 kg is suspended freely from one end. It is pulled to one side and then allowed to swing like a pendulum, Find the rod's kinetic energy at its lowest position
A bullet is fired through a board 13.5 cm thick, with a line of motion perpendicular to the face of the board. If the bullet enters with a speed of 387 m/s and emerges with a speed of 163 m/s, what is its acceleration as it passes through the boar..
At one instant, a mass (m = 2 kg) is at the location m and attached to one end of a spring with a spring constant ks = 60 N/m and a relaxed length L0 = 0.22 m. The origin is placed where the other end of the spring attaches to the ceiling.
