20 look at the clock and the data table below. based on the data and on your knowledge of potential and kinetic energy, what is the best conclusion you can make about potential and kinetic energy? the total amount of energy stays the same. the clock has the most potential energy at point b since it is moving the fastest. there is always more potential energy than kinetic energy. potential energy can never be 0, but you can have 0 kinetic energy.

The answer is The total amount of energy stays the same.

Explanation:

- According to the conservation law of mechanical energy, For a closed system that entails the presence of just conservative forces ( independant on the pathway between two points), the total mechanical energy of the system (which is the sum of potential and kinetic energies) remains constant  (stays the same).

- Clearly, the sum at any of the 4 points = 50 J..

i have no clue hope you find the answer

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
