Answer:

The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth

Explanation:

Although the the sun is roughly 400x wider than the moon, the moon is aproximately 400x closer to the Earth, and that is why seen from earth, sun and the moon appear to be the same size.

So answer is the sun is 400x wider than the moon, but the moon is also 400x closer to the Earth.

EXTRA:

There is a fenomenom called <em>blood moon</em>, when that happens, the moon appears to be bigger then normal (and it has a red glow about it).

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?
Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= \frac{600}{20} = 30

for a pH 2= [H+]= 10^{=2}

∴ [H+]=  \frac{10^{-2}}{30} = 3.333 * 10^{-4}

and pH is an antilog of [H+]= - log \frac{10^{-2}}{30} = 3.333 * 10^{-4}

∴pH = 3.47
