Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.15 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 530 m/s. Assume that the collisions of the particle with the walls are elastic.
(a) Find the mass density inside the box.
(b) Find the average pressure on the walls perpendicular to the particle's path.
(c) Find the average pressure on the other walls.
(d) Find the temperature inside the box.
A cubical piece of heat-shield tile from the space shuttle measures 0.11 m on a side and has a thermal conductivity of 0.059 J/(s m ·C°). How much heat flows from the outer to the inner surface of the tile in six minutes
Shooter shoots a bullet horizontally and has muzzle velocity of 460m/s and goes 45.7m. How can you do this with the range equation
A thermos contains 165 cm3 of coffee at 85° C. To cool the coffee, you drop two 14-g ice cubes into the thermos. The ice cubes are at first at 0° C and melt completely. What is the final temperature of coffee? Treat the coffee as if it were water.
At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accele..
The distance between points A and B along the open flow path is 500 ft. Calculate the total head loss between points A and B. Assume A and B are at the same elevation.
A stunt driver wants to make his car jump over 8 cars parked side by side below a horizontal ramp as seen in the figure below. With what minimum speed must he drive off the horizontal ramp to just barely make it across

A certain cable car is San Francisco can stop in 10 s when traveling at maximum speed. how far was the car from the dog
A particle with a positive charge 2e moves with a velocity V= (2i + 3j - k) m/s through a region where both a uniform magnetic field and a uniform electric field exist. Calculate the total force on the moving particle
The number of electrons in a copper penny is approximately 10*10^23, How large would the force be on an object if it carried this charge and were repelled by an equal charge one meter away?
An x-ray tube accelerates electrons from rest at 5.0×10 14th m/s(squared) power through a distance of 20cm . (Such high accelerations are possible because electrons are extremely light.) Find the electrons'velocity after this acceleration. Find th..
