A diver decides to do an experiment while diving off the coast of Vancouver. The diver will use a very heavy beaker, two artificial fish of the same volume (V = 110 cm), and a waterproof scale. One fish is made from plastic with an average density of plastic = 0.7 g/cm and the other fish is a drone made from metal with an average density of metal = 16.6 g/cm. The experiment is being performed underwater. Therefore, initially, the beaker is filled with water. The diver then places the beaker on the scale and sets the reading of the scale to zero ("tared"). The sketch of the configuration for each part of this question (see below) is provided in the figure. The density of water is 1 g/cm. fishing line string (a) (b) (c) (d) (a) Would the plastic fish float or sink in the beaker? If the plastic fish is tied to the bottom of the beaker by a string (ignore the mass of the string), will the reading on the scale increase, decrease or remain the same? What will the scale reading be? (Recall that prior to attaching the fish, the scale is tared to read zero. Also recall that scales detect force, but give their readings in terms of mass). kg (b) Would the metal drone fish float or sink in the beaker? If a metal drone fish is dropped into the beaker from above, being held up by a fishing line and does not touch the walls of the beaker, will the reading on the scale increase, decrease or remain the same? What will the scale reading be? kg (c) Now, the fishing line breaks. The drone fish is now at rest on the bottom of the beaker. Will the scale reading increase, decrease or remain the same, compared to the answer of part (b)? What will the scale reading be? kg (d) (Challenge question, not for marks!) The drone fish wakes up, finding itself at the bottom of the beaker. It then treads water in the middle of the beaker, not touching any part of the beaker wall. Will the scale reading increase, decrease or remain the same, compared to the answer of part (c)? What will the scale reading be?
