Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A physics laboratory is measuring the height of a tower using a measuring tape that has been incorrectly calibrated and consistently reads 1 meter shorter than the actual height. If the tower was measured to be 50 meters tall with this tape, what is the actual height of the tower?

💡 Hint: Consider how calibration affects accuracy.

Challenge 2 Hard

During an experiment, a student records the temperature of a solution as 30°C, but the thermometer used has a systematic error of +2°C. What is the actual temperature of the solution?

💡 Hint: Think about how to adjust for systematic inaccuracies.
