Afarmer plants corn in nutrient rich soil. the corn plants absorb nutrients from the soil in order to grow and perform life processes. after the corn plants mature, the farmer harvests the corn and sells it for human consumption. he continues to plant and harvest corn for many years without adding fertilizer. how will the continuous planting and harvesting of corn most likely affect the soil in which it is grown? a. the soil will become more fertile. b. the soil will begin producing its own fertilizer. c. the soil will change into igneous rock. d. the soil will become less fertile.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
