ROGERS 20:20 97% a universityofmanitoba.desire2learn.com Question 2 (1 point) A student measures the diameter of a disk fifteen times with a ruler that has a smallest division of 1 mm. The average of the 15 measurements is 17.04667 cm and the sample standard deviation is 5.595063x10-3 cm. The correctly rounded-off uncertainty (don't use scientific notation) is cm and the correctly rounded off value is cm. D View hint for Question2 Question 3 (1 point) The diameter of...

3. The potential energy of an object is given by P=m.g.h, where m is the mass, g is the gravitational constant (9.81m/s), and h is the height of that object above some reference point. If we measure m and h, as well as their uncertainties om and Oh, and we know the value of g, which is a constant, we want an algebraic expression for the uncertainty on the potential energy, op. (a) First, lets break this up into P...

You measure the length of a board with a ruler that is older and has a worn-down end. If you align the end of the board with the end of the ruler, what type of uncertainty does the end of the ruler contribute to the measurement? A) Random B) Systematic The average height of children in kindergarten in Winnipeg is found by measuring the height of one randomly-selected child in every kindergarten class in the city. What type of uncertainty...
