Answer: The answer is C, Yes, her star will have appeared to move very slightly to the west.
Explanation: If your looking at a certain star, it usually goes to the west at night time very slightly, it doesn't go to the east because the Earth's axis tilts mostly on the west side. So it makes it true.

1kg = 1000g
e
1 g = 1000mg
então
1 kg = 1 x (1000 x 1000)
1 kg = 1x 1.000.000
1 kg = 1.000.000mg
assim
1 comprimido -------------> 0,025 mg
x comprimido ------------> 1.000.000 mg ( só cruzar)
0,025(x) = 1(1.000.000)
0,025x = 1.000.000
x = 1.000.000/0,025
x = 40.000.000
<h3>1kg são feitos 40.000.000( Quarenta milhões de comprimidos)</h3>
Total internal refraction occurs when a ray of light meets the following conditions.
1. light falls from an optically dense material to a less dense material.
2. The angle of incident in the denser media must be greater than the critical angle.
In the case above the fiber-optic is optically denser than water. Since the light is incident to fiber-optic-water interface, then one condition is fulfilled.
Checking the other condition we carry out the calculation below;
n1sinФ1=n2sinФ2
where c ⇒critical angle
1.53 sinc = 1.33 sin 90
sinc =0.86928
c = 60.37°
The angle of incident is (65°-70°) is greater than critical angle.
With certainty, there would be no refraction. Total internal reflection would occur.
Answer: two way gravity is affected if somethings weight is doubled or grtavity gets weaker with distance
