Potato Physics Problem

Question

A raw potato was found to have a mass of 330 grams. The potato was sliced and the slices were set in a single layer on a piece of screen wire to dry in the sun. The potato was measured after 7, 14, and 21 days and found to be 212 g, 148 g, and 126 g, respectively.

Which is the independent variable in the experiment, and where would it appear in a data table?

Answer 1

Here days 7,14 and 21 are independent variable and the corresponding mass 212, 148 and 126 gm are dependent variable
