Answer:
Bathtub
Explanation:
Even though the water in a filled bathtub may be at the same temperature as water in a glass, the water in the bathtub has more thermal energy because it contains a greater number of water molecules.
When an electron in an atom absorbed a photon, the energy of the electron changed by 2.94 × 10⁻¹⁹. The frequency of the photon is 4.4 × 10¹⁴ Hertz .
<h3>How to calculate the frequency of photon ?</h3>
To calculate the frequency of photon use the expression
E = hv
where,
E = Energy
h = Planck's Constant
v = frequency (Hz)
Put the value in above formula we get
E = hv
2.94 × 10⁻¹⁹ = 6.6 × 10⁻³⁴ × v
v = 
= 0.44 × 10¹⁵
= 4.4 × 10¹⁴
Thus from the above conclusion we can say that When an electron in an atom absorbed a photon, the energy of the electron changed by 2.94 × 10⁻¹⁹. The frequency of the photon is 4.4 × 10¹⁴ Hertz .

Answer: D) protons.
The other option that would make the most sense would be electrons, however the mass of an electron is so small that is basically negligible, so it's not included in the atomic mass.
