The link below is a picture of the "Waning gibbus" phase, really hope that it helps you out :D
Answer:
1 mol contains 6.02 x 10^23 molecules. So 0.25 mols will contain 0.25 x 6.02 x 10^23 molecules.

Answer:
You transfer kinetic energy from you foot to the ball.
Explanation:
Energy cannot be created or destroyed.
Answer:
a) 12/323
b) 8/233
Explanation:
a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323
b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233
(hopefully I did this right)
