Answer:
Pressure
Explanation:
One of the theories propounded by the Kinetic molecular theory, and which also provides an explanation of the several gas laws, is the statement that the gas molecules in a container, travel in straight lines and are in constant collision with themselves and the walls of the container, thus exerting force. This force is the pressure which is defined as the force per unit area.
There is no loss of energy in the collisions involving the gas molecules and that is why their movement can be described as elastic. The descriptions of the behavior of gas molecules in the Kinetic Molecular Theory, give rise to Charles law, Boyle's Law, Avogadro's Laws, Dalton's Law, and Amonton's Law.
The answer is A. C. The equation has C, which is Speed of light squared
Answer: D. 
Explanation:
The energy 
of an electromagmetic wave is given by:
Where:
is the Planck constant
is the speed of light in vacuum
Then 
is the wavelength
Solving:
Answer:
0.3950m
Explanation:
Use conservation of angular momentum:
Let L be the angular momentum(a vector).
We know that:
and that the two masses have the same radius:
Hence, the weights are 0.3950m away .
Answer:
Dropping a stone from a height is work
Explanation:
Work is the action of a force through a distance.
w = fd
The Earth's gravitational attractive force is pulling the stone to its centre, so the Earth is doing work on the stone.
