A student conducted several tests on circular motion. In the tests, mass A was swung on a circularpath. Mass B provided the necessary force to balance mass A, resulting in a known radius as shownin the diagram.radiusmass Amass BThe student varied the masses and radius for each test. They measured the time for mass A to make 10rotations three times for each mass and radius, then averaged the three results to produce the table shown.Time for 10rotations (s)TestMass of A (g)Mass of B (g)Radius of circle (m)50500.12510250500.20013350500.25014450500.3751750750.12586.501000.12577502000.1258125500.125169250500.1252210750500.12527(a)Outline THREE different experiments conducted using the information from the table.(b)For Tests 5, 6 and 7, identify the dependent, independent and TWO controlled variables.(c)The student repeated all of the tests with 20 rotations.Would the experiment that used 10 rotations or the experiment that used 20 rotationsbe more reliable?
