What is the average mass of the 10 pennies? Report your value with correct significant figures.
What is the error (uncertainty) associated with each mass measurement due to the equipment?
What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation.
What is the standard deviation of the 10 mass measurements?
Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement?
Calculate the total mass of the pennies with associated uncertainty.
Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
Can you help me and explain the answers please.
