A homogenous mixture is a mixture that is uniform throughout and can be
separated by physical means. An example of which is the blood where its
composition is uniformly mixed throughout but it can be separated by
centrifugation, a physical means using the speed of rotation. Here, the denser
particles are forced to settle in the bottom and the lighter particles stay at
the top when rotated quickly.
Answer:
B. Two waves have displaced in opposite directions
Explanation:
Interference occurs when two waves meet at a point in space. When this occurs, two extreme conditions can occur:
- if the two waves are in phase (=displacement in the same direction), the amplitude of the resultant wave is equal to the sum of the amplitudes of the two waves:
A = A1 + A2
and this condition is called constructive interference
- if the two waves are in anti-phase (=displacement in opposite directions), the amplitude of the resultant wave is equal to the difference of the amplitudes of the two waves:
A = |A1 - A2|
and this condition is called destructive interference. Note that if A1=A2, the amplitude of the resultant wave is zero.
Answer:
Explanation:
Subtract both sides by 
:
Divide both sides by -2*a:
Add both sides by 
:
Subtract both sides by 
:
The input force will increase too because the more the ramp is increasing the more force is being put on the object going down the ramp... hope this helps ^-^
