Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.
Hope this helps (:
The reason to collimate the light source before utilizing the prism is that if white light enters the prism at various angles, some blue light will exit the prism at the same angle.
Prisms' Dispersion of Light. When light source travels through a triangular prism, these hues are frequently seen. The prism separates the white light source divided into its individual colors, which are red, orange, yellow, green, blue, and violet. Dispersion is the process through which visible light is divided into its various colors.
Since blue light has a shorter wavelength than red light and refracts more than the latter, it is bent more when white light enters a prism than red light.

Answer:
B. Repel each other
Explanation:
Two like charges have the same sign. Example an electron with a negative charge (-e) and another electron with same charge(-e). Or a proton with a positive charge (+e) and another proton with same charge (+e). Since each of these pair charges have the same sign, they will repel each other.
On the other hand, if the charges are opposite, ie negative charge and positive charge, they will attract each other.
B. Repel each other
Answer:
Acceleration is equal to the displacement of an object divided by the time the object takes to complete the path
Explanation:
In other words, you can say that acceleration is the increase in the rate or speed of something.
Note: acceleration can also be negative, which means that instead of increasing, decrease in the rate or speed will happen. Such an acceleration is called deceleration.
I hope it helped! Good luck!!
