Answer:

i hope it will be useful for you

Explanation:

F=5.6×10^-10N

R=93cm=0.93m

let take m1 and m2 =m²

according to newton's law of universal gravitation

F=m1m2/r²

F=m²/r²

now we have to find masses

F×r²=m²

5.6×10^10N×0.93m=m²

5.208×10^-9=m²

taking square root on b.s

√5.208×10^-9=√m²

so the two masses are m1=7.2×10^-5

and m2=7.2×10^-5

Consider the double-fluid manometer attached to an air pipe shown. If the specific gravity of one fluid is 14.514.5, determine t
kvv77 [185]

Complete Question

The complete question is shown on the first uploaded image  

Answer:

The  value  is  S_g_2  =  3.128

Explanation:

From the question we are told that  

  The specific gravity of the first fluid  is  S_g_1 =  14.5

  The  pressure of air is  P_a  =  81kPa  =  81*10^{3} \  Pa

  The  atmospheric pressure is  P_A  =  100 kPa  =  100 *10^{3}  Pa

Generally the specific gravity of the second  fluid is mathematically represented as

            S_g_2  =  S_g_1  * \frac{h_1}{ h_2 }  +  \frac{P_a  -  P_A}{\rho_w *  g *  h_2 }

Here  \rho_w is the density of water with value \rho_w  =  1000 \  kg/m^3

=>   S_g_2  =  [14.5 *  \frac{0.22}{0.4} ] +  [\frac{81*10^{3}-100*10^{3}}{ 1000 *  9.8 *  0.4} ]

=> S_g_2  =  3.128

How much brighter is a sun-like star than the reflected light from a planet orbiting around it?.
Digiron [165]

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.

Acetone is a flammable solvent used in the making of plastics. The density is 790kg/m3. to convert 790kg/m3 to g/cm3​
Artist 52 [7]

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
