mason notices that his boat sinks lower into the water in a freshwater lake than in the ocean. what could explain this?\no the boat is more dense in salt water.\no the boat is less dense in salt water.\no salt water is less dense than freshwater.\no salt water is more dense than freshwater.
Answer
Brief Explanations:
The buoyant force acting on the boat is given by Archimedes' principle ($F_b=\rho gV$). For the same boat (same weight and thus same buoyant - force needed to float), since the density of salt - water ($\rho_{salt}$) is greater than the density of fresh - water ($\rho_{fresh}$), the volume of water displaced ($V$) in salt water is less. So the boat sinks lower in fresh water.
Answer:
D. Salt water is more dense than freshwater.
