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