You can lift an elephant Oil point {graded} (a) A m : 90 kg student wants to elevate a M : 3200 kg elephant on a hydraulic lift filled with water ( ,0th = 1000 kg/m3) to a height of \"IO cm {labelled as h in the diagram}. If the radius of the student's cylindrical pipe, T1 : 0.3 m, determine the radius of the elephants pipe, T2? m- 1.7 (b) If we replace the water with oil [pm-g = 900 kg/mg}, will the relative height difference, h, between the student and the elephant increase, decrease, or stay the same? Explain your reasoning
