Advanced level 2026 Adamawa regional mock physics 3

Measure the average diameter, $d$ of the round object provided.

Carefully wrap the paper tape round the circumference of the round object. Make an ink mark on the two portions of the tape where they overlap.

Stretch out the tape and measure the distance between the two ink marks on it. Record the distance, $C$.

Repeat steps 1 through 3 for different round objects in order to obtain other values of $d$ and $C$.
