HURRY WILL MARK BRAINLIEST Farha makes the graphic organizer shown to review the characteristics of transistors.
BabaBlast [244]

Answer:

<em>C. It is made from three layers of semiconductors.</em>

<em></em>

Explanation:

<em>Bipolar transistors (pnp and npn) are usually made from a sandwich of three semiconductors layers</em>. The main charge carriers are holes and electrons. An npn transistor has two semiconductor junctions that share a thin middle positively enhanced region (the material is enhanced with impurities rich in holes which are the positive charge carriers), and a pnp transistor has two semiconductor junctions that share a thin middle negatively enhanced region (material is enhanced with impurities rich in electrons, the negative charge carriers).

Explain How can you tell that river water is suspension ?
andreev551 [17]

Answer:

Streams need vitality to move material, and levels of vitality change as the waterway moves from source to mouth.  

At the point when vitality levels are high, huge rocks and stones can be moved. Vitality levels are generally higher close to a waterway's source, when its course is steep and its valley slender. Vitality levels rise considerably higher in the midst of flood.  

At the point when vitality levels are low, just little particles can be moved (assuming any). Vitality levels are most reduced when speed drops as a waterway enters a lake or ocean (at the mouth).
