Answer:
Explanation:
Energy, E = 4.75 x 10^-19 J
Energy, E = hc/λ
where, λ is the wavelength, h be the Plank's constant and c be the velocity of light.
h = 6.63 x 10^-34 Js
c = 3 x 10^8 m/s
λ = (6.63 x 10^-34 x 3 x 10^8) / (4.75 x 10^-19)
λ = 418.73 nm
So, the colour of light should be violet.
True think of it like a satellite if it weren't for the earths gravity they would've kept going in a straight line up

Answer:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
Explanation:
One possible question can be:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
The answer to this question is contained in Charle's law, which states that for a gas at constant pressure, the volume of the gas is proportional to its absolute temperature:

Or also written as

By looking at this equation, we can find immediately the answer to our question: as the (absolute) temperature of the gas increases, the volume increases as well, by the same proportion.
