A lightyear is the distance light can travel in one year. If the sun is 150,000,000 km away, how many light years is the sun from the earth? Assume that light travels at a speed of $3.00 * 10^10 cm/s$.
Thanks for any help!?
distance divided by speed of light= 150,000,000/300,000= 500 seconds 8.3333 8.3 minutes now divide this by 60 x 24 x 365.25. so you will get answer= .000015823 light years.

A person on the earth is looking up at the sun, which is 92,900,000 miles away. The angle spanned by the sun at the person's eye is approximately 0.5 degrees. What is an estimate for the diameter of the sun?
As 0.5 degrees is quite a small angle the diameter of can be calculated as $rθ$, where r is the distance to the Sun and θ is the angle in...

How do the fusion reactions in the sun compare to the fusion occurring in larger stars and supernovas?
In a smaller star such as the main process of fusion from Hydrogen to Helium is the proton-proton chain reaction. This is where two protons combine under the strong nuclear...

Do planets actually revolve around the sun? Maybe they follow the sun around a more central Star in middle of Galaxy? Based on the heliocentric model of orbiting, how could the planets revolve around the sun this way, if this it were true?
No scientist seriously doubts the heliocentric theory, indeed evidence of it is available to anyone with a decent phone or very modest telescope and a few clear nights to observe...

If light takes 8 minutes to travel from the sun to Earth and 5 hours to travel from the sun to Pluto, what is the distance from the sun to Pluto?
Light takes about 5.5 hours to reach Pluto from . If you know the time that light takes to reach certain object, you can deduce the distance to that object...

Why are elements with atomic number 26 not formed by nuclear fusion in the cores of very massive stars?
When you fuse four protons and to make a helium-4 nucleus (and also absorb two electrons for charge balance), it's energetically favored because the product nucleus has less energy than...

Group 18 rarely combines with other elements. They are the "loners" or noble gases. Why do these elements not need to bond with other elements?
The main reason the noble gases do not need to bond with other is that their outermost subshells are filled. These are known as . Take helium for example. It...

What types of elements are generally involved in an ionic bond?
Metals gain full outer shells by losing electrons and go form positive ions. Non-metals do the opposite. The positive ion attracts the negative ion electrostatically thus forming an ionic bond.

How does ionic bonding affect the properties of the elements involved?
For example, sodium has a very low melting point (about 97.72 °C). But when sodium makes ionic bond with chlorine,it produces sodium chloride (NaCl), a compound with melting point of...
