Question

determining independent and dependent variables
study the table, which shows the length of a pendulum
and the corresponding time period it takes to make a
complete swing back and forth.
the length is the
the period is the
dependent variable
independent variable

Explanation:

An independent variable is a variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is a variable being tested and measured in a scientific experiment. In this case, the length of the pendulum is what is being manipulated (changed), so it is the independent variable. The time period (the period) is what is being measured in response to the change in length, so it is the dependent variable.

Answer:

The length is the independent variable. The period is the dependent variable.
