A gas always fills whatever container it's in. You will get a lot of answers
to your question, with various technical discussions that involve pressure
and temperature. The fact of the matter is that the only thing you can do to
change the volume of the gas is change the volume of the container it's in.
Answer:
The quantity of energy per photon is inversely proportional to the wavelength of the light.
Explanation:
Energy of light is given as
E = hf
where E = energy of the photons,
f = frequency of the light
If the number of photons = n
(E/n) = (h/n) f
Let (E/n) = E'
(h/n) = h'
But the frequency of light is related to wavelength through the relation
v = fλ
where v = speed of light = c
λ = wavelength of light
f = (c/λ)
E' = h' f
Substituting for f
E' = h' (c/λ)
h' and c are both constants, h'×c = K
E' = (K/λ)
So, the quantity of energy per photon is inversely proportional to the wavelength of the light.
Hope this Helps!!!
the answer is 1a as rearrange gives I = v divided by r
B. +Q, + W are the correct sign
