Answer:
Gases
Explanation:
The molecules in a gas are spaced very far apart.
They stay with the microscope as it moves around to different schools, and they are always located in the same classroom where the rest of the microscope is being used.
The formula to find the kinetic energy is:
Ek= 1/2 × m × v^2
1. Ek= 1/2×15×3^2
= 67.5 J
2.Ek= 1/2×8×4^2
=64 J
3.Ek= 1/2×12×5^2
= 150 J
4.Ek= 1/2×10×6^2
= 180 J
So the fourth dog has the most kinetic energy.
