Part 1: Make a graph of each set of data. For the first set, plot the start location data on the x-axis and the box's average sl

ide distance on the y-axis. For the second set of data, plot the mass of the marble on the x-axis and the average distance the box slides on the y-axis. Four start locations were chosen for this experiment. Why was the potential energy of the marble different at each location? What happened to the potential energy as the ball rolled down the ramp? Why did the box slide backwards when the marble hit it? What kind of energy did the box have as it was sliding? Where did this energy come from? What is the relationship between the marble's starting position and the distance the box slid? Part 2: All the marbles started at the 40-cm mark in this experiment. Were their potential energies the same? Why or why not? Comparing the marbles, was there any difference in the average amount that the box slid after catching the marble? What is the relationship? Do all of the marbles have the same amount of kinetic energy at the end of the ramp? How can you tell? Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph. According to your data, was your hypothesis for each experiment correct? (Be sure to refer to your data and graphs when answering this question.) Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas. 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 from real life where the principles demonstrated in this lab are evident.

What are some of the concerns associated with our increasing population and consumption of resources?
Ugo [173]

Explanation:

As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.

  • Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
  • Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
  • Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
  • High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

Makovka662 [10]

Answer:

Independent Variable: Hours of sleep

Dependent Variable: Test scores

Experimental Group: Group A

Control Group: Group B

Explanation:

Hours of sleep is the independant variable because it is the factor being tested by the teacher. This is the factor that can be controlled.

Test scores is the dependant variable because it is the factor being affected by the changes in the independent variable. This is the variable being measured.

Group A is the experimental group because this is the one that has been altered or changed from what is normal.

Group B is the control group because nothing is being changed in this group but simply measured as a basis for comparison.
