Answer:
8.5 kg
Explanation:
Angular momentum is conserved.
I₁ ω₁ = I₂ ω₂
I ω₀ = (I + mr²) ω
(49 kg m²) (40 rpm) = (49 kg m² + m (1.2 m)²) (32 rpm)
61.25 kg m² = 49 kg m² + (1.44 m²) m
m = 8.5 kg
The mass of the clay is 8.5 kg.
All matter is made up of subatomic particles that contain atoms. This is false statement.
Everything in the universe is made of matter, and so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: <u>protons, neutrons, and electrons</u>.
All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.
Matter is anything which have mass and occupy some volume.
On earth, solid, liquid, and gas are the most common states of matter. Not only is water the most common substance on earth, but it is also the only substance that commonly appears as a solid, a liquid, and a gas within the normal range of earth's temperatures.

A block of ice is solid water. When heat (a form of energy) is added, the ice melts into liquid water. If heat is removed from water vapour, the gas cools down and it condenses back into liquid water. Continue to cool the water (by removing heat), and it becomes solid ice.
