Answer:
The expression is Vmem = ΔV - I*Rax
Explanation:
According to the picture, if switch S is closed, the Cmem will be short. If Vcap = 0, the current flows through the capacitor only (not through Rmem), thus Vmem = 0 after closing S.
When C is fully charged, then we have:
Vmem = ΔV - I*Rax
Answer:
A. independent variable.
Explanation:
In this experiment, the types of box materials are a(n) independent variable, which is when you purposely change things or control them, hoping for a specific outcome.

Scientific evidence such as reflection and photoelectric effect has proven the wave-particle model of electromagnetic radiation to be true.
<h3>What is electromagnet radiation?</h3>
Electromagnetic radiation is radiation produced as a result of the interactions of the electric and magnetic fields.
Some forms of electromagnetic radiation include:
- radio waves
- microwaves
- ultraviolet radiation
- visible light
Electromagnetic radiation can be described using a wave model or a particle model.
The wave property of electromagnetic radiation include:
- diffraction
- reflection
- refraction
The particle property of electromagnetic radiation include:
- photoelectric effect
- Compton effect.
Therefore, the wave-particle model of electromagnetic radiation is correct because it can be backed up by experiments and evidence.
