Answer:
Pressure wil be greatest at R [coz due to capillary action, coz it's small cross-sectional area]
The answer is C. nebular are star nurseries. When the massive gas being collapsing in its own weight. Local areas of gas begin to coalesce under gravity. Due to enormous pressure, nuclear fusion begins and a protostar is formed. The protostar grows into the sun as more hydrogen fuses at the core. The planetesimal materials at the edges of the protostellar discs coalesce to form planets that orbit the star.
answer is 36
because the formulae of momentum is
mass×velocity
Based on Einstein's theory of gravity, if the sun and its mass were to suddenly disappear, earth would stay in its current orbit for a few minutes before taking off into space.
<h3>
What would occur to our world if the sun were to suddenly vanish?</h3>
The Earth would be drawn to a new center of gravity if the sun disappeared. Earth's gravity would change, as would that of the rest of the solar system, and Earth would begin to drift into space since there would no longer be a steady source of energy from the sun. It is a foolish dream to think that life could exist without the sun forever. Humans could be able to survive for a while in some sort of base, such as a nuclear-powered dome.
The good news is that there wouldn't be many living things for the radioactive waste to endanger; however, there also probably wouldn't be any liquid water to cool the power system. All photosynthetic species, including plants and algae, would die if just the sun's light persisted.
