Aneighbor kid is doing a science fair project about the conservation of energy. he is rolling a basketball down a ramp to show that mgh = 1/2mv^2. however, every time the experiment is run, the results show that mgh does not equal 1/2mv^2. however, if a second identical upward ramp is added, the ball very nearly goes back to its original height (so virtually no energy is being lost. perplexed, your (knowing you are taking physics) asks you what is wrong. what is your response?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
