Answer 1

Answer:

Here is the answer for your 3rd question :

Mass = 50g

Volume = 20 cm^3

Density = Mass / Volume

= 50 / 20

= 2.5 g/cm^3

Since, the Density of the substance is greater than the Density of water, it will sink in water.

The volume of water displaced = 20cm^3

Mass of water displaced = Velocity × Density

= 20 × 1

= 20g

Hope my answer is correct & will help you.
