Answer:
Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth - Sun distance.
The earth all the way around is 196.9 million miles

I really hope this helps i am in middle school and this must be a high school question.
Answer:
The final velocity of the object is 330 m/s.
Explanation:
To solve this problem, we first must find the acceleration of the object. We can do this using Newton's Second Law, given by the following equation:
F = ma
If we plug in the values that we are given in the problem, we get:
42 = 7 (a)
To solve for a, we simply divide both sides of the equation by 7.
42/7 = 7a/7
a = 6 m/s^2
Next, we should write out all of the information we have and what we are looking for.
a = 6 m/s^2
v1 = 0 m/s
t = 55 s
v2 = ?
We can use a kinematic equation to solve this problem. We should use:
v2 = v1 + at
If we plug in the values listed above, we should get:
v2 = 0 + (6)(55)
Next, we should solve the problem by performing the multiplication on the right side of the equation.
v2 = 330 m/s
Therefore, the final velocity reached by the object is 330 m/s.
Hope this helps!
Answer:
The helium contained in the Sun's atmosphere was produced by fusion of hydrogen to helium in the Sun's core. Since planets including the sun where all formed at the same time, Jupiter's atmosphere also contains Helium.
Explanation:
1) the helium in the suns atmosphere from the original helium and any helium the sun has produced from the nuclear fusion of hydrogen.
2) the helium present in Jupiter's atmosphere came from the helium in the matter that produced our solar system.
3) the helium found in the suns core comes only from the nuclear fusion of hydrogen
