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?

Answer;

The independent variable is the number of dry cells, and

The dependent variable is the length of time the bulb works.

Explanation;The main variables in a given experiment are the dependent variable and independent variable.An independent variable is the variable that is changed or controlled in a scientific experiment. Its purpose is to determine the effects of dependent variable.Dependent variable is the variable that is being tested and measure in a scientific experiment. in this case, the independent variable is the number of dry cells , while the dependent variable is the length of time the bulb works.

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.
