The difference between a solid and a gas is that the particles are more conjoined together in a solid, when in a gas the particles are more spread out.
Carbon compounds move through plants and animals, the ocean, the air, and throughout our planet. Carbon present in our atmosphere as carbon dioxide contributes to the"Greenhouse Effect" and related global warming. Carbon cycle used to described the flow of carbon in various form such as carbon dioxide CO2, organic matter, and carbonates through the atmosphere, body of water, terrestrial biosphere, and lithosphere.
Answer:
a) Angular speed(w) = 2.02rad/sec
b) 73J ( It is Inelastic Collision)
Explanation:
Given:
Mass=45kg
Length on each side = 1.5m side which is hangs vertically from a frictionless pivot at the center of its upper edge.
We need to calculate
(a) What is the angular speed and
(b) To know why the angular momentum conserved but not the linear momentum

The heat transferred is -30J
When the gas undergoes compression, work is done on the gas and its internal energy increases.
According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW
The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.
Therefore, the heat given to the gas is given by,
Thus, an amount of heat equal to 30 J flows out of the system.
