A small solid sphere of mass M0, of radius R0, and of uniform density ρ0 is placed in a large bowl containing water. It floats and the level of the water in the dish is L. Given the information below, determine the possible effects on the water level L, (R-Rises, F-Falls, U-Unchanged), when that sphere is replaced by a new solid sphere of uniform density.
Read it to me
The new sphere has density ρ = ρ0 and radius R < R0
The new sphere has mass M = M0 and density ρ > ρ0
The new sphere has mass M = M0 and radius R > R0
The new sphere has radius R > R0 and density ρ < ρ0
The new sphere has radius R = R0 and density ρ < ρ0
The new sphere has density ρ = ρ0 and mass M > M0
My answers:
F
F or U
R or U (this is the one I think may be incorrect...may be just U)
R or F or U
F
R
I believe the key is whether the mass is increasing (water level will rise) or decreasing (water level will fall). I'm unclear as to which of my answers is wrong.
Thank you very much for your help.
