Final answer:
The scenario described can be explained by Newton's 3rd Law of motion.
Step-by-step explanation:
The scenario described, where a car hits a mosquito and the mosquito hits back equally, can be explained by Newton's 3rd Law of motion. This law states that for every action, there is an equal and opposite reaction. When the car hits the mosquito, it exerts a force on it, and in turn, the mosquito exerts an equal force back on the car.
