Position is a relative measurement. If you want to know how far away in object is you need to know where you're measuring from. That is, distance always requires two points. Velocity is the time rate of change of position. If position is a relative measurement then so must be its rate of change. This means the statement I am moving is meaningless. It is not a meaningful thing to say that and object is moving without saying what it is moving with respect to. As an example imagine getting up and walking around on an airplane while it is in flight. you do not have to run 600 mph to get to the front of the plane you can simply walk around just like you're on the ground. That is because in your frame of reference the plane is not moving at all. It is the earth below that is moving. But the people on the ground think the plane is moving in the earth is at rest. Both people are correct because each observer has their own frame of reference. The only universally true statement is that there is relative motion between the plane and the ground. Every observer can agree on the fact but they will disagree on the speed of the earth and the plane. That is because motion is a relative measurement. In a similar way if someone asked how far away is Paris? Your answer would be different than mine because we live in two different locations. Neither of us are wrong but that is because Paris is not a definite distance away from every point in the universe. That is a commonsense thing for everyone, but for some reason it's easier to get mixed up about velocity. We get used to thinking that the earth is somehow stationary.
A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. ... The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

Answer:
Explanation:
Given that,
The wavelength of light,
The speed of light,
We need to find the frequency of light. We know that,
Where
f is the frequency
So,
So, the frequency of light is .
She feel warm due to sun shining on her back which shows the transfer of energy due to Radiation Mode of heat transfer.
Because in this case we do not need any medium to transfer the heat and all energy is transferred due to electromagnetic waves.
She feels warm sand under her feet which shows the heat transfer due to conduction mode.
Because in this mode of heat transfer the heat is transmitted by direct contact.
A cool breeze is blowing from the water which shows the heat transfer due to convection mode.
Here thermal energy is being transferred by the moving medium molecules.
Evidence for the particle nature of light are not: 1. refraction, 2. many colors of light, 3. diffraction. These are all phenomenon that support wave theory of light. Evidence for particle nature of light is photoelectric effect. Because it was discovered that you need discrete energies of light to eject electrons from a metal surface and not continuous as the wave theory of light suggests.
