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.

Answer

Brief Explanations:

The independent variable is what is changed in an experiment. Here, the number of dry - cells is being changed. The dependent variable is what is affected by the change in the independent variable. The length of time the bulb works is affected by the number of dry - cells.

Answer:

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