Use the HR diagram below to answer the question. Labeled HR diagram. The main sequence slopes from the upper-left of the diagram, which is blue, to the bottom-left of the diagram, which is red-orange.

An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom.
