Answer: the density of the rock
55.91g/ml
Explanation:
The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:
Volume of water substract the mass of the rock:
And that is 142.5 ml - 86.59g =
Answer 55.91 g/ml
So the density of the rock is 55.91g/ml

Without the statements, I can't specifically answer your question. But, I can present the largest piece of evidence we have for the Big Bang Theory.
Over the course of <em>many many </em>years, we have noticed something. Everything is expanding outwards.
We can observe this, and realise that since things are expanding outwards, or, away from something, everything once came from a fixed point.
Life and the universe started from one point, and every single thing in our cosmos is still expanding away from it. =)
