Simon and his friends are working on an experiment to determine the most common blood type group in california. which of these methods would be the best form of data collection? a. survey their own family members to find out their individual blood types; this data would represent blood type groups in the entire population of california. b. survey an area with a high latino population to find out the blood type of every individual; this data would represent blood type groups in the entire population of california. c. offer a free blood–type testing camp in a school laboratory and collect data; this data would represent blood type groups in the entire population of california.

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.
