I believe it is D because if the mass is smaller then greater the acceleration for it to be equal force. Hope this helps! Sorry, if I'm wrong.
Answer:
it says that matter cannot be created or destroyed so the number of atoms is the same after chemical reactions
Answer:
D
Explanation:
The gravity is pushing the water downward so Wayne could go down but the water is pushing Wayne to go up which would make him float.
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
