Answer:
F=1.65 x 10²⁶ N
Explanation:
Given that
Distance ,R= 3.34 x 10¹² m
Mass m₁= 2.78 x 10³⁰ kg
Mass ,m₂= 9.94 x 10³⁰ kg
we know that gravitational force F given as
G=Constant
G=6.67 x 10⁻¹¹ Nm²/kg²
Now by putting the values
F=1.65 x 10²⁶ N
Therefore the force between these two mass will be 1.65 x 10²⁶ N.
Answer:
All 88 constellations are based on figures that originated in Greek and Middle Eastern mythology. (<em>Correct</em>)
The α star in a constellation is usually brighter than the β star. (<em>Correct</em>)
All stars are part of some constellation. (<em>Correct</em>)
The modern constellations have English names rather than Latin like the ancient ones. (<em>Correct</em>)
Explanation:
Constellations were grouped by different civilizations as mean to be oriented when they were making observations of the sky (they could see as maps of certain regions). Each constellation is an arrangement of several stars in a specific figure (animals, mythological characters and objects), things that were important for that civilization.
The letter 
is given to the brightest star in a constellation while the other letters of the Greek alphabet are assigned to the other stars that belong to that specific constellation according to their brightness. For example in the Orion constellation the brightest star is Betelgeuse so it is classified with an ; 
to Rigel, the second in brightness and so on. That classification system was established by the astronomer Johann Bayer in 1603.
The modern constellations have English names, for example the constellations of Telescopium, Fornax, Sculptor, Chamaeleon, among others.
As constellations represent maps of different regions in the sky, any star will be related with them. For that reason is correct to say that all stars are part of some constellation.
The answer would be:
The comb gains electrons.
The hair loses electrons.
In chemistry, the charge depends on the electrons and protons. The electron will give negative charge and proton will give the positive charge. Proton is located in the nucleus of the atoms so it won't easily move like electron which located in the orbit in the atoms perimeter. So, ignore the option with the proton.
If the combs become negatively charged, that means it gain some electron. Since something gain electron, that means another thing is losing an electron. That electron comes from the hair.
Questions in this category that include the words "This graphic shows..."
or some such, frequently fail to include any graphic. When no graphic is
included, it must follow as the night follows the day that no physics is pictured
in the scene. Inertia is a very popular subject, often appearing in scenes
where physics is pictured. Sadly, however, in an environment that is totally
devoid of graphics, projectiles and the inertia they carry are seldom to be found.
