Pascal knows that a falling body accelerates at a constant rate, and he also knows that the same is true of a ball rolling down a ramp, as in the figure. Is the force that moves the ball the only force acting on it? Are there any other forces that do work on the ball?

For this question look at the hydropic diagram water that is heated by the sun evaporates. select the number that represents it.

Write the balanced chemical equation forphotosynthesis.

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
