Answer:
D) directly, inversely
Explanation:
The energy of a photon of light is directly proportional to its frequency and inversely proportional to its wavelength.
Frequency is the number of waves that passes through a point per unit of time.
Wavelength is the is the distance between successive crests or troughs on a wave.
Mathematically, frequency is related to wavelength and velocity using;
Energy = h x f
where h is the Planck's constant
f is the frequency
Since c = f ∧
where f is the frequency of the wave
∧ is the wavelength of the wave
c is the speed of light
So;
f = c/∧
Therefore;
E = 
From the equation, we see an inverse relationship between E and wavelength and a direct one with frequency.

Chemical=B
Mechanical=C
Nuclear=A
Electromagnetic=D
Thermal=E
I think these are right but if not I’m sorry
Hope I helped :]
Different:
1. number of moons
2. size of rings
3. mass
4. temperature
5. type of rings
i might be wrong though.
