Q. Two cubes, one silver and one iron, have the same mass and temperature. A quantity Q of heat is removed from each cube. Which one of the following properties causes the final temperatures of the cubes to be different?
Q. How much heat does it take to increase the temperature of 4.50 moles of a diatomic ideal gas by an amount 40.0 if the gas is held at constant volume? The gas molecules can translate and rotate but not vibrate.
A cart carrying a vertical missile launcher moves horizontally at the constant velocity of 30.1 to the right. It launches a rocket vertically upward. The missile has an initial vertical velocity of 40.33 relative to the cart.
1.76- block at rest on a ramp of height. While the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 12.0 that has a coefficient of kine..
A planet moves in an elliptical orbit around the sun. The mass of the sun is Ms. The minimum and maximum distances of the planet from the sun are R1 and R2, in that order.
A 37-kg girl is bouncing on a trampoline. All through a certain interval after she leaves the surface of the trampoline, her kinetic energy decreases to 215 J from 430 J. How high does she rise during this interval? Avoid air resistance.
Calculate the total amount of energy that flows into the space between the capacitor plates from to , by first integrating the Pointing vector over the surface that connects the edges of the two circular plates, and then integrating over time.
A 160 m wide river flows due east at a uniform speed of 4.05 m/s. A boat with a speed of 7.2 m/s relative to the water leaves the south bank pointed in a direction 39o west of north. What is (a) magnitude and (b) direction of the boat's velocity r..
