1. Which of the following depends on the inertial mass of an object (as opposed to its gravitational mass)?

The acceleration given to the object by a compressed spring.

The weight of the object on a bathroom-type spring scale.

  The time the object takes to fall from a certain height.

2.What would you consider the uncertainty to be in this estimate? (Use the provisional rules we have developed so far.)

3. The student is told that the accepted value is 1.85 g/cm3. What is the discrepancy between the student\'s best estimate and the accepted value?

4.Part 1 - A student measures the density of a liquid five times and gets the results (all in g/cm3) 1.8, 2.0, 2.0, 1.9, and 1.8. What would you suggest as the best estimate based on these measurements?

Solution

The best estimate is 1.8 as the variance from the accepted value of 1.85 is the least.
