A solid, homogeneous sphere with a mass of m0, a radius of r0 and a density of ρ0 is placed in a container of water. Initially the sphere floats and the water level is marked on the side of the container. What happens to the water level, when the original sphere is replaced with a new sphere which has different physical parameters? Notation: r means the water level rises in the container, f means falls, s means stays the same. A)
The new sphere has a density of ρ = ρ0 and a mass of m < m0.

B)
The new sphere has a density of ρ = ρ0 and a radius of r > r0.

C)
The new sphere has a density of ρ < ρ0 and a mass of m = m0.

The options are r, f, and s. Rises, Falls, Stays the same.
