A series of 3 identical pool balls are placed next to each other in a horizontal line at rest. A 4th identical pool ball collides elastically with the first ball at a velocity of 5 m/s. After all of the collisions in the line take place elastically, the velocity of the last pool ball in the line will be:

3 red balls, 4 blue balls, and 3 green balls are randomly placed in a line. What is the probability that there is at least one red and at least one blue between each pair of green balls?

Four identical bowling balls are placed on the corners of a square drawn on the ground...

Four identical bowling balls are placed on the corners of a square drawn on the ground whose sides are each .2 meters long. If the mass of each ball is 4kg, a)What is the magnitude of the net gravitational force acting on one of the balls due to all others, b)what is the magnitude and direction of the resulting acceleration of that ball? Please give full steps so I can follow along. TIA

Two identical concave mirrors are set facing each other 2.8 mapart. A small lightbulb is placed halfway between the mirrors. A small piece of paper placed just to the left of the bulb prevents light from the bulb from directly shining on the left mirror, but light reflected from the right mirror still reaches the left mirror. A good image of the bulb appears on the left side of the piece of paper. what is the focal length of each...

There are 7 balls in a bag. They are identical except for color. 3 are red, 2 are white and 2 are blue. You are to draw 1 ball from the bag, note its color, and set it aside. Then you are to draw a second ball from the bag and note its color. a. Make a tree diagram to show all possible outcomes of the experiment. Label the probability associated with each stage of the experiment on the appropriate...

3. (a) Two ideal gases are placed in separate, identical steel boxes. Each box has an identical pinhole through which the contained gas may effuse. One gas is Xe, while the other gas is an unknown––but elemental–– gas. The Xe totally effuses in 32.0 minutes, while the unknown gas totally effuses in 23.5 minutes. What is a likely identity for the unknown gas? Show your work. (b) A quantity of the tryptamine alkaloid psilocin, whose molecular weight is 204.27 g...

Two balls are placed, one above the other, and dropped from a height of 1.47 m. The bottom ball has a mass which is 7 times the mass of the top ball. They are dropped from rest. When the balls strike the floor, they have a head on, elastic collision with one another. (Assume that the bottom ball strikes the floor, instantly reverses direction, and then collides with the top ball, which is still travelling downward.) How high will the...

Two balls are placed, one above the other, and dropped from a height of 1.4 m. The bottom ball has a mass which is 10 times the mass of the top ball. They are dropped from rest. When the balls strike the floor, they have a head on, elastic collision with one another. (Assume that the bottom ball strikes the floor, instantly reverses direction, and then collides with the top ball, which is still travelling downward.) How high will the...

Four identical particles of mass 0.738 kg each are placed at the vertices of a 4.28 m x 4.28 m square and held there by four massless rods, which form the sides of the square. What is the rotational inertia of this rigid body about an axis that (a)passes through the midpoints of opposite sides and lies in the plane of the square,(b)passes through the midpoint of one of the sides and is perpendicular to the plane of the square,...

Four identical masses of mass 700 kg each are placed at the corners of a square whose side lengths are 15.0 cm. Part A) What is the magnitude of the net gravitational force on one of the masses, due to the other three? Part B) What is the direction of the net gravitational force on one of the masses, due to the other three? -toward the center of the square -outward the center of the square
