Chapter 1, Problem 1STP

To determine

The correct option.

Answer to Problem 1STP

The correct option is (A).

Explanation of Solution

Introduction:

The bar graph between objects and the time taken by object to reach ground is shown below,

  

In the graph, along x -axis lies the objects and along y axis lies the time required for each object to fall. We know that the independent variable is plotted along x -axis and the dependent variable along y -axis. Here, in the graph, object is the independent variable and the falling time is considered as the dependent variable.

Conclusion:

Hence, the dependent variable is the falling time and the correct option is (A) falling time.
