14. what should bart's conclusion be?
bart believes that mice exposed to
radiowaves will become extra strong
(maybe he's been
reading too much
radioactive man).
he decides to
perform this
experiment by
placing 10 mice
near a radio for 5
hours. he compared these 10 mice to
another 10 mice that had not been
exposed. his test consisted of a heavy
block of wood that blocked the mouse
food, he found that 8 out of 10 of the
radiowaved mice were able to push
the block away. 7 out of 10 of the
other mice were able to do the same.
15. how could bart's experiment be improved?

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.
