Question

why the piece of stone shink to the bottom of the tub where as the piece of wood floats​

Answer 1

Answer:

This ratio between weight and volume is called density. An object that is less dense than water can be held up by water, and so it floats. An object that is more dense than water will sink.

The logs that float are less dense than the logs that sink.

Testing out a few samples of wood illustrates this. A piece of cedar, which is rather light, will easily float on top of water. Oak, on the other I hope it will help you please add me to the brain list

Answer 2

Answer:

An object will float if the gravitational (downward) force is less than the buoyancy (upward) force. ... This explains why a rock will sink while a huge boat will float. The rock is heavy, but it displaces only a little water. It sinks because its weight is greater than the weight of the small amount of water it displaces
