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.

When light reaches a barrier or the edge of an opening it diffracts, which means that the light _________.

Reptile [31]

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.

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters. (a) Determine the

Igoryamba

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.

$Then, f(x) = \frac{1}{1.05 -0.95} =10$

1 - 0.95 = 0.05, 1.05 - 1 = 0.05

$\ minimum, f_(x) = \frac{0.05}{1.05 -0.95} =0.5\\\\$

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
