Ice.
Because the hollow ball is larger than the solid one. It displaces enough of the fluid to equal its weight, so it floats.
I'm afraid you don't understand what energy is. It is not a solid substance that either floats or sinks. Energy is a force, not a thing.
ice cubes, iceburgs. do they float or sink and that might answer your question
If the density is more than 1 (gram per cc), then a solid lump of it sinks in water. Less than 1, it floats.
t If it sinks it is higher densitiy, but if it floats it's lower density. If it hangs aroung the middle it's the same density!
Suspensions are mixtures in which the density of the liquid and the solid are such that the solid neither sinks not floats in the liquid but is suspended throughout.
A solid that has a density greater than the density of the medium it is placed in (i.e. water). So a piece of lead is more dense than water, and so it sinks. Styrofoam is not very dense, and it floats.

put them both in a tub of water and if one floats its not as dense as the other if it sinks its more dense
Put it in water. If it floats, it's less dense. If it sinks, it's more dense.
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.

The solid state of water is less dense than its liquid state, which is why ice floats on water. The solid state of nearly all other substances is more dense than the liquid state and sinks in the liquid state.
