Omar wrote a hypothesis about batteries called dry cells.

If more dry cells are connected end to end, a light bulb will work longer because there is more energy available.

What are the variables in his hypothesis?

The independent variable is the number of dry cells, and the dependent variable is the length of time the bulb works.

The independent variable is the length of time the bulb works, and the dependent variable is the number of dry cells.

The independent variable is the number of dry cells, and the dependent variable is the amount of energy available.

The independent variable is the amount of energy available, and the dependent variable is the number of dry cells.

The independent variable is the number of dry cells, and the dependent variable is the length of time the bulb works.

Explanation:

From this experiment, we can clearly ascertain that the dependent variable is the length of time the bulb works and the independent variable is the number of dry cells.

The independent variable is usually the cause of the phenomenon observed. The dependent variable is the effect produced by the independent variables. The number of battery is independent. Duration of time the bulb works depends on the number of battery used.
