Procedure for calibrating the force probe

[smh745]

Hi,

I need help for 3 questions


1) Describe qualitatively the procedure for calibrating the force probe.

2) when determining the acceleration over a timeinterval, LoggerPro provides the following statistics :

Average 0.107
Standard Deviation 0.120
Number of Points 54

Determine how many significant figures you should include in your average, and write the value here with the correct number of significant figures. Be sure to explain clearly how you arrive at your answer.

3) If quantity A is proportional to quantity B, describe how a graph of A vs. B should look.



I have tired to answer these question and I got wrong results.


I need help to solve these questions


thank you

Do you mind sharing your wrong results with us? Perhaps we could point out where your tripping up?

1) The procedure for calibrating the force probe involves several steps. First, the probe should be mounted in a stable position and connected to a computer or data logger. Next, a known weight should be attached to the probe and the corresponding force reading should be recorded. This process should be repeated with several different known weights to establish a relationship between the force readings and the actual weights. Finally, the data should be analyzed to determine the calibration curve or equation that relates the force readings to the actual weights.

2) The number of significant figures in the average value should be determined by the number of significant figures in the smallest value used in the calculation. In this case, the smallest value is the standard deviation of 0.120, which has 3 significant figures. Therefore, the average should also be reported with 3 significant figures, giving a value of 0.107.

3) If quantity A is proportional to quantity B, the graph of A vs. B should be a straight line passing through the origin. This means that as the value of B increases, the value of A also increases in a linear fashion. The slope of the line represents the proportionality constant between A and B.
