<h2>Answer : Electromagnetic energy</h2><h3>Explanation :</h3>
The solar panel usually combines multiple photo voltaic cells. Electromagnetic energy is used to power a solar panel. As the electromagnetic energy or rather radiations from the sun reaches to Earth in the form of radiation which is then collected by these photo voltaic cells. As the term solar energy simply suggests that the energy is coming from the sun. Thus, electromagnetic energy coming from the sun was produced when electric charges inside the sun change their potential energy.
Answer:
Ka2 values should be used in obtaining pKa2 in the Henderson–Hasselbalch equation
Explanation:
During first dissociation from H3PO4 to H2PO4-, ka1 will be used, and from H2PO4-to HPO4-, ka2 values will be used, hence a buffer solution containing H2PO4-and HPO4-will use ka2 in obtaining pKa2 in the Henderson–Hasselbalch equation.
The correct answer is A. apples coming in many different varieties.
This is because people who grow apples mix different kinds of apples in order to produce new ones, which means they are selecting the qualities they want the new apple to have in order to get the best results. B, C, and D are incorrect because that is the normal behavior or appearance of these animals - there is nothing extraordinary about them that was created thanks to selective breeding..
