A small solid sphere of mass Mo, of radius Ro, and of uniform density Po 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 he new sphere has mass M = Mn and radius R...
