Answer:
x is approximately 95.495
Explanation:
The given information are;
One lunar month = 30 days
The measured time between the first and third quarters = 14.9 days
Therefore, the angle of rotation for 30 days = 360°
The angle of rotation for 14.9 days = 14.9×360/30 = 178.8°
Therefore, whereby 2·θ = 178.8°
θ = 178.8°/2 = 89.4°
Therefore, given that the angle at the tangent from Sun to the Moon = 90°, we have;
The angle between the line from the Sun to the Moon = 90° - 89.4° = 0.6°
From sine rule, we have;
1/(sin 0.6) = x/(sin 90°)
x = (sin 90°)/(sin 0.6°) ≈ 95.495
x = 95.495.

Answer:
We could reduce the force or increase the mass of the object.
Explanation:
Using the definition of force, according to Newton's second law, (F = ma) the acceleration is directly proportional to the force and inversely proportional to the mass. Therefore, if we want to reduce the acceleration of an object we have two options:
- We could reduce the force
- We could increase the mass
In both cases a will decrease.

White light is light that's made up of ALL colors.
If you have a source of white light and you want red light,
then you have to REMOVE all the other colors from the
white light somehow.
That's what a red filter does. The dye in the filter has chemicals
that absorb every color of light except red. Then, red light is the
only thing left to come out of the other side.
(If the light going into the filter had no red in it, then the filter
would appear black, because there wouldn't be any light
coming out of it at all.)
