Question

Quizplus · Accepted Answer

The weight of the lobster on the ocean floor is the same as its weight above the surface. However, since water is denser than air, there is an upward force (buoyant force) acting on the lobster when it is in water. This buoyant force reduces the effective weight of the lobster, making it weigh less when it is above the surface. Therefore, the lobster's weight is less above the surface compared to its weight on the ocean floor.
