If the billiard ball is going at the constant speed and contains its mass then the momentum WONT be changing. But realistically you have external forces like friction and air resistance changing the velocity thus changing the momentum. In this case momentum is not conserved because you're introduction an external force.
Diffraction is the slight bending of light when it passes around the edge of an object. The amount of bending depends on the relative of the wavelength of the light wave to the size of the opening. If the opening is much larger than the wavelength the bending will be almost unnoticeable but if the two are equal or closer in length then the diffraction will be noted. Therefore, the correct answer is bends.
Answer:
The proportion of flanges that exceeds 0.99 millimeters is 0.6
Explanation:
Given;
integral range of [0.95, 1.05]
Let X be a variable with uniform distribution over the given range.

1 - 0.95 = 0.05, 1.05 - 1 = 0.05

interval = 10 - 0.5 = 9.5
F(x) = 10x + 9.5
When, X exceeds 0.99 millimeters, then the proportion of flanges will be;
P (X > x) = 1 - F(x)
P( X > 0.99 ) = 1 - 10(0.99) + 9.5
P( X > 0.99 ) = 0.6
Therefore, the proportion of flanges that exceeds 0.99 millimeters is 0.6
