A meter stick is made out of aluminum. The scale is accurate at 40°C. Suppose an intrepid student living in Alaska takes the meter stick outside on a very cold winter day to measure the length of a concrete paving stone with dimensions of 10 inches by 10 inches at 40°C. What length will the student measure, if the outside temperature is −46°C? (Give your answer in cm at −46°C.
Round your answer to at least two decimal places.)

(4 points) A steel meter stick has a calibrated (accurate) length at 20.0°C. It is used to measure the length of a thin zinc rod at 20.0°C which gives a measured length of 0.9580 m. The zinc rod is measured again, but now with both the steel meter stick and zinc rod at 85.0°C. Find the absolute error in the length of the zinc rod as measured by the steel meter stick at 85.0°C. The coefficient of linear expansion of...

Required (hand in) 1. By using a 2-meter stick (like the one in lab) marked in millimeters and a stopwatch that measures to 1/100h of a second, you decide to measure the speed of a motorized toy car that travels at a constant velocity. You measure out a 162.0cm interval with the 2-meter stick and time how long it takes the car to travel that distance using the stopwatch. Repeating the experiment 5 times you get the following time data:...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
