A rock is suspended from a scale reads 20.0 N. A beaker of water is raised up so the rock is totally submerged in the water. The scale now reads 12.5 N. What is the density of the rock?

p1.(1).pngFig. 15-2 shows the displacement of a wave at a given position as a function of time and the displacement of the same wave at a given time as a function of position. Determine the speed of the wave.

As a rock sinks deeper and deeper into water of constant density, what happens to the buoyant force on it?
