Ambersnyder, Your answer would be A).
Answer:
Volume of the cube is 2*2*2 = 8cm^3.
Divide the weight (40g) over the volume (8cm^3).
Density is 5g/cm^3. Definitely not gold.
Explanation:
Given what we know, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy.
<h3>What is a Photon and what energy does it release when being emitted?</h3>
- A photon is a particle.
- This means that it is one of the smallest forms of matter that we can study.
- Photons form electromagnetic fields.
- Therefore, when being emitted by an electron, photons release electromagnetic energy.
Therefore, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy due to the properties of the photon being emitted.
