Asked by Alessandra Romano
1. The Following instruments are available in your laboratory. What would be the absolute uncertainties in the measurements made with these instruments?
A. Ruler
B. Protractor
C. Watch
D. Scale
2. By using the instruments from the task 1, you have determined that it takes 3s for a toy car to travel through the distance of 162cm. What are the relative uncertainties of the distance and time measurements? Which measurements is the least uncertain?
3. Calculate the average speed of the toy car. Decide whether you can use the weakest link rule to determine the relative uncertainty in speed estimation. Determine the range of possible values for the actual speed of the car.
4. Why do we need to calculate relative uncertainty? Why isn't absolute uncertainty enough?
