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...

You hold a ruler that has a charge on its tip 2 cm above a small piece of tissue paper to see if it can be picked up. The ruler has −10 µC of charge. The tissue has 3 g of mass. What is the minimum charge required to pick up the tissue paper? Answer: ________ uC The answer is NOT -1.31e-10 C / -.000131uC

For the 10cm position on the ruler, I got a distance of 10.795
cm of the movement of the gauge. I'm struggling to find the force
of friction (f) from that to find the coefficient of kinetic
friction.
1. From the 10-cm position on the ruler, let the steel bearing ball roll into the kinetic energ gauge positioned at the bottom of the ruler. 2. Measure the distance along the flat surface that the gauge moves before stopping. We recommend...
