For this problem, you have already determined the cell density of a culture in a flask. You take a 1 ml volume containing 10 cells, and add it to a 10 ml tube of media to get 1 cell/ml. You set up 12 of these tubes all with 1 cell/ml (so you have enough to make a growth curve).
These tubes are incubated for 12 days total, and you sample 1 ml each day from the appropriate tube (day 1 is tube 1, day 2 is tube 2, etc.) and spread plate on media plates (1 ml).

Cell numbers on the plates are as follows.
Day - 1 1 CFU/ml Day - 7 10000
Day - 2 10 Day - 9 1000
Day - 3 100 Day - 10 100
Day - 4 1000 Day - 11 10
Day - 5 10000 Day - 12 10
Day - 6 10000

A. How fast was the growth during exponential phase?

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.
