Which of the following helps explain why experiments involving speed and velocity are important. A. Experiments involving speed and velocity are not important because they have already been throughly investigated by scientists and there is nothing more to learn

B. Experiments involving speed and velocity are important they have not been investigated much and scientists still do not fully understand how speed and velocity are related

C. Repeated experiments with airplanes and how their velocity changes as a result of environmental conditions like wind can help scientists develop a model for flight paths and launch times to minimize fuel usage

D. Repeated experiments that change motivational foods for tortoises on tracks can help scientists determine preferred eating habits
