Inside the house where the temperature is 20∘C20∘C, we measure the length of an aluminum rod with a micrometer MADE OF STEEL. (A micrometer is a device which measures distances very accurately.) We find the rod to be 10.0000 cm long. If we repeat this measurement outside where the temperature is-13.7 ∘∘C, what result would we obtain? Caution: the size of the micrometer is also affected by the temperature, so we no longer obtain the true length of the rod...

Phy 1010 – Chapter 2 Activity: Measure your reaction time. Requires a ruler and a friend to help you. Hold the index finger and thumb of your dominant hand about 2.5 cm apart, and have a friend hold a ruler vertically in the space between your fingers and thumb. Note the position of the ruler relative to your index finger. Your friend must release the ruler, and you must catch it (without moving your hand downward) as quickly as you...

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...
