The 'Bulge', the 'Disk', the 'Spiral Arms', and the 'Halo' those are four parts of a spiral galaxy. Try finding out the many different types of galaxies to understand which is which.
Explanation:
Given that,
A person walks 9.0 km directly east and then turns left and heads directly north for 12.0 km.
We need to find his displacement from the starting position.
We know that,
Displacement = shortest path covered
For direction,
Hence, this is the required solution.
The populations of insects increases I believe? Please correct me if I’m wrong
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.
Because they eventually erode and then break and end up forming underwater.
