Solution

The answer is B. a contact force. When James hit the white cue ball, it moved and hit the #2 ball. This is a contact force because it required the cue ball to physically come into contact with the #2 ball to cause it to move.

Two friends, Neha and Sneha, decided to play the game pockets billiard on their holiday. This game is similar to the carom game, except but it has 6 holes on the board to strike the balls into it. This game consists of 15 numbered color balls, and 1 cue ball, which is used to strike the other 15 numbered color balls to the holes. These balls are arranged in the pyramid form. The first player strikes them using the white ball(cue ball) to break the formation and then tries to sink the ball into the holes. Each player takes alternate turns to strike the balls. (Note: Ignore the cue ball while taking the total number of balls.)  1. If Neha plays first, then the probability that she successfully sinks the ball numbered 10 is1212151151015 2. If Sneha plays secondly without replacing the ball 10, then the probability that Sneha sink the ball numbered 13 is11410151315115 3. The probability that Neha sinks a ball is an odd number is1315114115815 4. The probability that Sneha sinks a ball is a number divisible by 6 is215115114815 5. The probability that Sneha sinks a ball is a number not divisible by 6 is1315215115114

A cue ball in a frictionless environment collides with three stationary billiard balls. How does the momentum of the three billiard balls change due to the collision?Multiple choice question.The momentum that the group of balls gained is equal to the momentum that the cue ball lost. Momentum is conserved.The momentum of the group of balls does not change, nor does the momentum of the cue ball. Momentum is conserved.The momentum that the group of balls gained is less than the momentum that the cue ball lost. Momentum is not conserved.The momentum that the group of balls gained is more than the momentum that the cue ball lost. Momentum is not conserved.Need help? Review these concept resources.
