Hello there!
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
V(voltage) = I(current)R(resistance)
substitute in the values
V = 15 * 0.10
V = 1.5 volts
Answer:
because a smaller cylinder shaped wheel, called the axel ,connects the wheels on a car.
