Answer:

Galactic disk

Explanation:

Galactic disc's are composed mostly of the galaxy's stars and a gaseous component mostly composed of cool gas and dust. The stellar population of galactic discs tend to exhibit very little random motion with most of its stars undergoing nearly circular orbits about the galactic center. This circular orbit maintains the galaxy's rotation momentum.

Answer: C. Galactic disk

Explanation:

The part of the Milky Way which allows the determination of it rotational direction is known as the Galactic disk. This disc are shaped because they contain gases which are rich and dynamically young. It is also a part of a group of a galaxies disc is a component of disc galaxies, known as spiral galaxies and lenticular galaxies.

What color does a red and blue jacket look through a green filter​ put over a red filter
pickupchik [31]

Answer: black

Explanation:

A colour filter is a filter that lets only one colour pass through it. For example, a red filter lets only red colour pass through it, while a green filter lets only green light pass through it.

In this example, we have a red and blue jacket. At first, we put a red filter: this filter lets pass throuhg only the red light. Then, we put a green filter: this filter lets pass only green light through it. However, there is no green light coming from the previous filter (since only red light passes through it), so the jacket appears black (no colours).

A Ferris wheel is a vertical, circular amusement ride with radius 9.5 m. Riders sit on seats that swivel to remain horizontal. T
Kruka [31]

Answer:

928.34 N

Explanation:

Radius=r=9.5 m

Time period of revolution=T=7.6 s

Mass of rider=m=57 kg

We have to find the rate of change of the rider's momentum at the bottom of the ride

According to Newton's second law of motion

F_{net}=ma_c

N-mg=mr\omega^2

N=mg+mr(\frac{2\pi}{T})^2

Where \pi=3.14,g=9.8 m/s^2

Using the formula

N=57\times 9.8+57\times 9.5(\frac{2\times 3.14}{7.6})^2

N=928.34 N

Hence, the rate of change of the rider's momentum=928.34 N

Convergent faults ___.
Anna35 [415]
<h3><u>Answer;</u></h3>

can form mountains and volcanoes.

Convergent faults <u>can form mountains and volcanoes</u>.

<h3><u>Explanation;</u></h3>
  • Convergent plates boundary are created when two tectonic plates collide such that one of the converging plates will move beneath the other forming a subduction zone. The process is called subduction.
  • <u>Convergent faults happen when plates move toward one another , and can form volcanoes  and also create mountains.</u>
  • At convergent plate boundaries where two plates move toward each other a compressive stress takes place
