The diagram shows a ball resting at the top of a hill. Which statement best describes the energy in this
system?
х
O The potential energy in the system is greatest at X.
The kinetic energy in the system is greatest at X
O Total energy in the system decreases as the ball
moves from X to Y
O Total energy in the system increases as the ball
moves from X to Y

Plz will mark! the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

Ais a landform that is formed at the mouth of a river from the deposition of sediment carried by the river as the water flows.

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
