Answer:
is a reflection.
The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted). When the object is that the focal point, the image is at infinity.
Explanation:
C did the most effort, but A walked the longest, so a reasonable answer is that they all did the same amount of work, as B simply mediates.
Answer: In an exothermic reaction, the products have less energy than the reactants.
Explanation: There are two types of reactions:
1. Endothermic reactions: These are the reactions in which energy is required in the reaction. The energy of the products are more than the energy of the reactants.
2. Exothermic reactions: These are the reactions in which energy is released in the reaction. The energy of the products is less than the energy of the reactants.
Hence, in an exothermic reaction, the products have less energy than the reactants.
