Which is larger an atom or a molecule

Answers

Answer 1
Answer: MOLECULE;
For example, a hydrogen atom forms one bond, an oxygen atom forms two, and carbon forms four bonds. Look at that molecule of water again - each hydrogen has one bond, and the oxygen in the middle has two bonds. Molecules can be much bigger.

Suppose the angular separation of two stars is smaller than the angular resolution of your eyes. How will the stars appear to your eyes?

Answers

Answer:

The two stars will look like a single point of light.

Explanation:

When the angular separation is smaller than angular resolution, the eye will not be able to resolve the stars thus they will appear like a point source of light.Angular resolution is one of the limit that our eyes can see. Angular resolution describes how much our eyes can distinguish two things apart which depends on the angle created by the incoming light rays from the two object. A smaller angle, very small angle for light rays to enter the eye thus little or no details for the eye to distinguish.

Final answer:

When two stars are closer together than the angular resolution of our eyes, they appear as a single point of light.

Explanation:

When the angular separation of two stars is smaller than the angular resolution of our eyes, they will appear as a single point of light to our eyes. This is because our eyes cannot distinguish the individual stars due to their close proximity. This is similar to how distant stars appear as pinpoints of light.

Why is using two thin blankets in bed usually warmer than one thick one?

Answers

Air pockets. Between two blankets, a pocket will form. Then, it will heat up along with the body heat.
i think it is because a big thick blanket has more room in it. if you have two thin blankets there isn't a whole lot there so it keeps the warmth in. 

Gravity causes___ objects to accelerate

Answers

Gravity causes falling objects to accelerate.
all? 

Most likely all.

The reason is since the acceleration of gravity is about 10 m/s^2 this means that gravity would cause all objects to accelerate at the same rate. So most likely all objects. 

The demand for your hand-made skateboards, in weekly sales, is q = −3p + 700 if the selling price is $p. You are prepared to supply q = 2p − 500 per week at the price $p. What price should you sell your skateboards for so that there is neither a shortage nor a surplus?

Answers

Answer:

you should sell your skateboards at $240

Explanation:

The price p to sell your skateboards for so that there is neither a shortage nor a surplus is the price that makes equal the quantity of sales and the quantity of supply, so p is equal to:

q (sales) = q (supply)

-3p + 700 = 2p - 500

700 + 500 = 2p + 3p

1200 = 5p

1200/5 = p

$240 = p
