The length of the ramp, the speed and weight of a ball
Explanation:
A controlled experiment needs to be done with constant values and one variable value. According to this experiment, the only variable value is<u> the angle of the incline</u>. And the student must hold constant the <u>length of the ramp</u> where each ball rolls. <u>The ball speed</u> and its<u> weigh</u>t.
By doing this, He can determine how far a ball rolls over the same length ramp, depending on the variable angle of the incline.
Frameshift mutations are genetic mutations that cause nucleotide changes in the frameshift sequence via insertions and deletions, which are collectively named indels
The source of the data is very important, even if the data isnt necessarily false information, its important to make sure the source is credible and their test was set up correctly so the data can be valid.
