The answer would be 200000 J. the equation for kinetic energy is 1/2 mass times velocity squared. 1/2 of 1,000 is 500. and 20*20 is 400. So, multiply 400 by 500, and that gives you your answer,
Answer:
c
Explanation:
plants decrease the levels of carbon dioxide in the atmosphere due to the process of photosynthesis
When equilibrium is reached, the solution is said to be saturated. A solution containing a higher concentration of solute than its solubility is said to be supersaturated.
