Explanation:
1. The Centauri star system consists of 3 stars and is about 4.37 light-years away from Earth. (A light-year is the distance that light travels in a year.)
2. We see the visible spectrum which consists of colors red, orange, yellow, green, blue, indigo, and violet. (The visible spectrum is the range of light that our eyes can detect.)
3. Because air has a lower index of refraction than water, the light beams making up the image of the fish I see bends as it leaves the water and enters the air. (Index of refraction determines how light bends when moving from one medium into another.)
4. When I look at my reflection in the mirror, the light reflects off the mirror at an equal but opposite angle as it hits the mirror.
5. When looking into a concave mirror the center is further away from you than the outside edges. (Concave mirrors cave in.)
6. Forklift drivers are careful to look in the convex mirrors placed at blind intersections in the warehouse.
7. is transparent and the light goes through without distortion.
8. The electromagnetic spectrum refers to any or all of the possible wavelengths of "light", both the visible light and invisible light.
9. The transmission of light through a medium means it goes through it.
10. The absorption of light by a medium means it is absorbed by it.
When the contracting gas and dust from nebula become so dense and hot that nuclear fusion starts
Answer:
if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
Explanation:
The incident light is generally random, that is, it does not have a polarization plane, when the first polarized stops by half, this already polarized light arrives at the second polarizer and the causticity passes
I = I₀ cos² θ
therefore if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
To solve this problem it is necessary to apply the concepts related to the Gravitational Force, for this purpose it is understood that the gravitational force is described as
Where,
G = Gravitational Universal Force
Mass of each object
To solve this problem it is necessary to divide the gravitational force (x, y) into the required components and then use the tangent to find the angle generated between both components.
Our values are given as,
Applying the previous equation at X-Axis,
Applying the previous equation at Y-Axis,
Therefore the angle can be calculated as,
Then in the measure contrary to the hands of the clock the Force in the particle 3 is in between the positive direction of the X and the negative direction of the Y at 71 ° from the positive x-axis.
