# Post Lab on Tension: Qs 1 & 2 Answered, Need Help with Q3

• Habibrobert
In summary, the conversation discusses post lab questions related to tensions and mass transfer between two carts. The first two questions involve determining whether the tensions are identical and if they decrease when mass is transferred from one cart to another. The third question involves calculating the mass of a hanger based on the tension in all the strings when the system is held still.

Hello,

I am stuck on this post lab question. I have tried to answer questions 1 and 2 but I am unsure of my answers, could someone verify them to make sure I did this correctly? Also, I have no idea how to do number 3! I included screen shots of the problem.

Thanks very much.

1. I agree with your answer - the tension are identical, so one cannot distinquish between the two.
2. When some of B's mass is transferred to A the tensions between the two carts will decrease, so I agree with you again - the pull is less in 2.
3. The tension in all the strings, or all of the tensions, are the same throughout the system when held still. Form this you can calculate the mass of the hanger.

## 1. What is the purpose of a post lab on tension?

The purpose of a post lab on tension is to analyze the results of an experiment that was conducted to measure tension, and to draw conclusions based on those results. It allows scientists to evaluate the accuracy and precision of their measurements, and to identify any sources of error that may have affected the results.

## 2. What are the first two questions of a post lab on tension about?

The first two questions of a post lab on tension typically focus on the experimental setup and the materials used. They may ask about the type of equipment and instruments used to measure tension, and the specific materials that were used in the experiment.

## 3. Can you provide help with question 3 of the post lab on tension?

Yes, I can provide assistance with question 3 of the post lab on tension. Please provide the specific question and any relevant information or data from the experiment, and I will do my best to help you find the answer.

## 4. How can I improve my understanding of tension from a post lab?

One way to improve your understanding of tension from a post lab is to carefully review your experimental setup and data, and to compare your results with expected values or theoretical calculations. You can also research the principles and equations related to tension, and seek additional resources or explanations from your instructor or other experts in the field.

## 5. What should I include in my conclusion for a post lab on tension?

In your conclusion for a post lab on tension, you should summarize the results of the experiment, discuss any sources of error or uncertainty, and draw a final conclusion about the relationship between the variables that were measured. You may also include suggestions for future experiments or improvements to the experimental setup.
