Submit your age structure diagrams from the lesson; be sure you have correctly labeled each diagram. You had to create age structure diagrams for three countries in the Population Age Structure lesson. Submit your age
structure diagrams from the lesson. Be sure you have correctly labeled each diagram and the country that it is for. Use
those diagrams to answer the questions for part 2
Part 2:
Answer the following questions about your diagrams:
1. Which country has the youngest population?
2. What percentage of Canada's 2005 population was between the ages of 30 and 44?
3. What is a cohort? Provide an example.
4. A human population is said to be "aging" If its members age 0-14 make up less than 30 percent of the population
and those age 75 and over make up more than 6 percent of the population. Do any of the countries in your lab have
an aging population? If so, which ones?

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.
