Answer:The energy in fossil fuels (coal, oil, gas)
Explanation:
Answer:
The answer is option B: the ball´s force on the bat
Explanation:
Using Newton's third law (action and reaction) that says: If two bodies interact the force of one exerts on the other is of equal magnitude, direction and opposite direction
Therefore, if the bat hits the ball (action), the ball (reaction) with a force on the bat of equal magnitude, but opposite direction
The total oxygen atoms that are exprected in the vinegar and baking soda reaction is three oxygen atoms.
Answer: B. 3

Answer:
B-Refraction
Explanation:
Refraction is the change in direction of a wave as it passes from one medium to another.
The curved surface of a convex lens bends the light rays just enough to make them meet at a focal point.
The answer is both.
For kinetic energy:
KE = 1/2*m*v^2 = 0.5*20,000 grams*5 = 50,000 J
For gravitational potential energy:
Pe = mgh = 20,000 grams*9.81 m/s^2*2 m = 392.2 J
