<u>Answer:</u>
"The Sun's diameter is about five times that of Earth" is not true about the sun.
<u>Explanation:</u>
The Sun at the pivotal of the solar system is a star and covers 99.86% of the total mass of the system. Approximately 73% mass of the sun is due to hydrogen gas while nearly 25% mass due to helium and for the remaining mass small amount of heavier elements like carbon, oxygen, neon and iron are responsible.
The diameter of the sun is 864,000 miles or 1.39 million km or 109 times of the Earth while mass is 330,000 times of the Earth's mass. Sun is a almost perfect sphere of hot plasma with internal convective motion responsible for production of a magnetic field through a dynamo process. And the most important source of energy on Earth for life.
Answer:
W = 5586[J]
Explanation:
Work in physics is defined as the product of force by a distance.
where:
W = work [J]
F = force = m*g [N]
m = mass = 300 [kg]
g = gravity acceleration = 9.81 [m/s²]
d = distance = 1.9 [m]
Now replacing:
![W=m*g*d\\W=300*9.81*1.9\\W=5586[J]](https://tex.z-dn.net/?f=W%3Dm%2Ag%2Ad%5C%5CW%3D300%2A9.81%2A1.9%5C%5CW%3D5586%5BJ%5D)

glad to help out!
The atomic mass is roughly equal to the sum of protons and neutrons of an atom.
9 protons + 10 neutrons = 19
Atomic mass of Flourine is 19.
I'm not sure about the distance to the nearest star, but it's probably about 4 light-years (L-y).
1 L-y = 1.86 * 10E5 mi/sec * 3600 sec/hr * 24 hr/day * 365 day/yr
1 L-y = 5.9 *10E12 mi and 4 L-y = 2.3 *10E13 mi distance to star
2.3 * 10E13 mi / 900 mi/hr = 2.6 * 10E10 hr hours to star
2.6 * 10E10 hr / (24 hr/day) = 1.1 * 10E9 day days to star
1.1 * 10E9 day / 365 day/yr = 3 * 10E6 yr = 3 million years to star
