Malachi went sledding on the snow day. Through careful measurement and calculation, he was able to determine that his potential energy at the
top of the hill was 10,000 J and his kinetic energy at the bottom of the hill
was only 9,000).
Explain why his potential and kinetic energies were not equal. Where
did the energy go? Think about what happens in REAL life.

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
