Question

eluded testube place in pure milk sinks to standard level M some water is mixed with the milk will the testube sinks more or less explain or give reason

Answer 1

The density of milk decreases by adding water. So the weight of milk-water mixture displaced by immersed part of the tube is decreased as compare to the loaded tube. It becomes lighter in weight. So the tube sinks more and will float only when the weight of this milk-water mixture displaced by the tube is equal to the weight of loaded tube.
