Question

11.Which object float on water and which object sinks in water? Explain​

Answer 1

Answer:

$\large\mathcal{\red{Answer :-}}$

Explanation:

When the object has density less than 1 g cm-1 then it floats on the surface of water, because, it always displaces more weight of water than its own weight. ... As buoyant force is less than its own weight, therefore, it sinks.

Answer 2

$\huge\pink{\mathfrak{answer}}$

Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That's because air is less dense than water.
