Question

John has a toy boat made from wood. He placed the wooden boat on the pond and it floats. He attached a piece of lead on one end of the string and ties the other loose end onto the boat, assuming the specific gravity of wood is 0.5 and the density of the pond water is equal to the density of the pure water, determine the smallest amount of mass of lead that will sink the boat.

Answer 1

In my point of view as density = Mass/ Volume

So what ever it is if the ship is made of metal it will sink and if in case of wood the it will float .

This can be explained as .Think a point that the water is a huge quantity in our planet earth and almost 60–70 percent of the earth is covered by water , placing the Ship is like placing a object in a water of bucket.

As the mass of the water in sea is greater that mass of the object. So it depends upon the surface area of the object that occupied .

In my point of view, The boat will be float with 20 percent inside of the sea.and also based on weight in the ship.

Thank you
