Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A student measures the diameter of a small ball using both a meter stick (±1mm) and a vernier caliper (±0.1mm). The meter stick reads 50.0mm, while the vernier caliper reads 50.3mm. Which measurement is more reliable, and why?

💡 Hint: Consider the precision of the instruments.

Challenge 2 Hard

During an experiment, a researcher consistently measures the weight of a sample to be 2.5g using a faulty balance which has not been calibrated. If the true weight was actually 3.0g, identify this type of error and suggest a way to avoid it.

💡 Hint: Think about how maintaining equipment can affect accuracy.
