Question

1) I stick a rocket on an asteroid and fly it past Neptune.

A) How much force will I feel from Neptune compared to the force Neptune feels from me?

B) How much effect will I experience from the force from part A compared to how much effect Neptune will experience from the force from part A?

2) A) Explain the process, step by step, that most Jovian planets go through to gain heat inside themselves.

B) Explain one reason why Terrestrial planets can't use the same process to gain heat.

3) My spaceship ends up in another solar system and I crash on an ocean planet (one that consists of at least 50% liquid water). A) Where was that planet formed and why?

B) What must have happened to get the planet to be like it is now?

Answer 1

(1)

A) The same gravitational force would feel as that of the neptune feel force from the person.

B) The effect of force would be same.

2) jovian planets like jupiter and neptune would have high density inside the interior with high pressure. the main compounds are hydrgen , metals and helium in and gases forms. the compression is still going on these planets and not yet completed. therfore due to slow contraction it would emit heat slowly towards the surface.

3)

A) the planet may be formed near to the boundary of solar system, which may be in dwarf state like pluto.

B) after consuming whole fuels inside the star it would slowly gets cooled, and woulld have lead to some ice crystal formation making this an ocean of ice or water crystal.
