Initially, the translational rms speed of a molecule of an ideal gas is 554 m/s. The pressure and volume of this gas are kept constant, while the number of molecules is doubled. What is the final translational rms speed of the molecules?
What are magnitude and direction of the force
A spring with spring constant 14 hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 and released. The ball makes 17 oscillations in 16 seconds. What is it the mass of ball.
Find out the critical angle for the glass-synthetic interface (same as for the glass-diamond interface). Sketch a picture of the incoming ray as it interacts will all subsequent interfaces.
Two negative and two positive point charges (magnitude = 3.64mC) are positioned on opposite corners of a square (each side = 0.155 m).Determine the magnitude of the force on each charge.
Four equal charges of +2.5×10-6 C are placed on the corners of one face of a cube of edge length 15.0 cm. A charge of -2.5×10-6 C is placed at the center of the cube. What is the magnitude of the force on the charge at the center of the cube?
Calculate escape velocity for an object started at the surface of the earth, going straight up. Neglect any complications due to the earth turning.
An Atwood machine consists of two masses, = 7.1 and = 8.7 , linked by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius = 0.40 and mass 0.70 .Determine the magnitude of the acceleration of..
After the collision, the 0.177 kg puck has a speed of 1.38 m/s at an angle of 27? to the positive x axis. Examine the velocity of the 0.302 kg puck after the collision.
The temperature of the air in a resonator is 15°C, when a tuning fork vibrates at one end, the spacing between tow successive resonances is found to be 50 cm. find the frequency of the tuning fork.
A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.30 T. The field is then adjusted so that an electron will follow a circular path of the similar radius when it is projected perpendicularly into the field with t..
What is the highest speed with which a 1550 car can round a turn of radius 76 on a flat road if the coefficient of static friction between tires and road is 0.50.
Clifford is in a real hurry, however, and skips the speedramp. Starting from rest with an acceleration of 0.39 m/s2, he covers the same distance as the ramp does, but in one-fourth the time. Illustrate what is the speed at which the belt of the ra..
