The best explanation of the observation of the researcher is that some of the energy is converted into thermal energy (option C).
<h3>How does energy transfer?</h3>
Energy, according to the law of conservation of energy, cannot be created nor destroyed but transformed.
According to this question, a researcher found that the amount of light energy produced in a neon lighted sign was less than the amount of electrical energy used.
This suggests that some of the energy is converted into thermal energy.

2. A
Explanation:
1.Which of the following statements about light waves is true? check all correct answers
A.They come from sources across space reason is that a light can travels form its source and its moves across the space
B.They travel in a straight line from their source reason is that the type of light that undergo these is called parallel ray of light
C.They can travel through any type of material reason not all materials light can penetrate through e.g wall
D.They can be reflected by some types of material reason is that some materals reflect light rays e.g polished mirror
Answer:
Electric field will be 
Explanation:
We have given potential difference between the two plates = 15000 volt
Distance between the plates = 
We have to find the electric field strength between the plates
Potential difference between the plates is equal to 
So electric field strength will be 
So electric field will be
