Alyssa observed a flock of small birds in her yard. the birds visited a pair of feeders that her parents put out for them and splashed in the birdbath. which question is a nonscientific question that she might ask about the birds? what color are the beaks of the small birds that visit the feeders? does having a birdbath present affect the feeding habits of the birds? at what time of day do the most birds visit the feeders? would the birds still visit if the seed in the feeders was changed?

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.
