Answer:
The value is 
Explanation:
From the question we are told that
The specific gravity of the first fluid is 
The pressure of air is 
The atmospheric pressure is 
Generally the specific gravity of the second fluid is mathematically represented as

Here
is the density of water with value 
=> ![S_g_2 = [14.5 * \frac{0.22}{0.4} ] + [\frac{81*10^{3}-100*10^{3}}{ 1000 * 9.8 * 0.4} ]](https://tex.z-dn.net/?f=S_g_2%20%20%3D%20%20%5B14.5%20%2A%20%20%5Cfrac%7B0.22%7D%7B0.4%7D%20%5D%20%2B%20%20%5B%5Cfrac%7B81%2A10%5E%7B3%7D-100%2A10%5E%7B3%7D%7D%7B%201000%20%2A%20%209.8%20%2A%20%200.4%7D%20%5D)
=> 
It is about a billion times brighter.
<h3>What is the brightness of a star called?</h3>
- A star's apparent magnitude, or how bright it seems to be from Earth, and absolute magnitude, or how brilliant it looks at a standard distance of 32.6 light-years, or 10 parsecs, are words used by astronomers to describe stellar brightness.
<h3>How bright are planets compared to stars?</h3>
- Although planets and stars light up the night sky, planets usually appear much brighter than most stars.
- Astronomers use astronomical scales to measure the relative brightness of celestial bodies, and many planets fall within the range easily visible to the eye.

Answer: 0.790 g/cm3
Explanation:
The density of acetone is 790 Kg/m3.
To convert from Kg to g we multiply by 1000 (1 Kg = 1000 g)
To convert from m3 to cm3 we multiply by 10∧6
So, The density of acetone in (g/cm3) = (790 x 1000) / (10∧6) = 0.79 g/cm3
Answer:
C. 32.7%
