it takes light from the sun about three minutes to reach mercury how many hours does it take light from the sun to reach Neptune

Kazeer [188]

The time taken to reach the Neptune planet is 4.2 hours

<h3>What is the time taken?</h3>

We can see that the speed of light has the value of 6.7 * 10^8 miles per hour . We also know that the solar system is composed of the sun and the planets. The distance of the between the sun and mercury is 35,000,000 miles while the distance between the sun and Neptune is 2.8 x 10^9 miles.

This implies that the ratio of the distance from neptune to the sun and that of mercury to the sun is; 2.8 x 10^9 miles/3.5 * 10^7 miles hence Neptune is eight times farther from the sun than mercury.

The time taken for light to reach Neptune from the moon is;

Distance = 2.8 x 10^9 miles

Speed = 6.7 * 10^8

Time = 2.8 x 10^9 miles/6.7 * 10^8

= 4.2 hours

Missing parts;

Mercury is the closest planet to the Sun, with an average distance of 35,000,000

miles.

It takes light about 3 minutes to travel from the Sun to Mercury.

Neptune is the farthest, with an average distance of 2.8 x 10 to the power of 9 miles from the Sun.

How many times farther from the Sun is Neptune than Mercury?

What is the history of Galápagos Islands? I need help!

vitfil [10]

Hello LonelyPerson, to answer your question.
The Galápagos were officially annexed by Ecuador in February 12 1832 and were named "Archipelago del Ecuador.". It is still today officially a province of Ecuador. Ecuador claimed the Galápagos Islands just three years before their most famous visitor, Charles Darwin, dropped anchor on the Beagle and stepped ashore and into history.

Now that you have identified the components of DNA, can you describe how these components bind together to form a DNA molecule?

omeli [17]

The question is incomplete. The complete question is attached below.

Answer:

1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.

2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.

3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .

4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
