Answer:
C. Maximum power point tracking.
Explanation:
A. Direct current: It is also called DC in which electric current flows consistently in one direction.It is used in batteries and cells.It is not used in solar system .Therefore, it is false.
B. Alternating current : It is also called AC . The AC is used in domestic electricity.The current in which direction of electron is reversed after at regular intervals .It is not used for solar cells.Hence, it is false.
C. Maximum power point tracking:It is also called power point tracking. It is used in charge control in solar cells.it is a technique which is used to extracting maximum available power from PV ( photovoltaic cells) solar system.It is a technique that is used to adjust load connected to solar cells and increase their energy output.Therefore, it is true.
D. Electromagnetic induction:It is a process for producing EMF due to change in magnetic field. It is not used in solar system. Therefore, it is false.
Answer:C. Maximum power point tracking.
I know that some plant cells are made from cellulose, and one of the main goals of the cell wall is to strengthen and support the cell. So, I think, the answer(s) are: cellulose and increased strength to the cell
C. Amplitude
The amplitude and hight interfere in sound. The higher and the more amplitude there is, higher will be the sound and vice versa.
