So i believe is exercise:)
Answer:
Frequency
Explanation:
The property of waves that remains unchanged as it crosses the boundary of one medium to another is the frequency of the wave.
As a wave moves from one boundary to another, the wavelength and the speed of the wave changes.
The speed of the wave is product of wavelength and frequency. Also, the wavelength of the wave is function of the distance between successive crests or troughs of a wave.
The frequency of a wave is the number of waves that crosses a medium per unit of time.
The correct answer is B (Inertia)
We define inertia as the resistance to change of the state of motion. That is, a body tends to remain in its state of motion or rests unless an external for acts on it. The quantity depends on the mass of the body. If the body is heavy, it requires a large force to overcome the inertia.
The two sides of the aluminium pop can have opposite charges. Overall the can is electricity neutral; it's just that the positive and negative charge has been separated from each other. We can say that the charge in the can has been polarized. In general terms, polarization means to separate into opposites.
