Which one of the entries below describe Torricelli's experiment ? Please choose one: a.Take two hemispheres of identical dimension, with leak proof flanges on the rim, close them onto each other and evacuate the air inside. Then apply a gradually increasing force to open and record the magnitude of the force that overcomes the atmospheric pressure and opens the hemispheres apart. b.Fill a bowl with mercury, dip a glass pipe into it while holding it vertical and measure the height of mecrury column starting from the bottom of the bowl. c.Fill a glass tube of length about a meter completely with mercury, close the tip with a finger, turn it upside down and dip the open end into a bowl of mercury. Then remove the finger, while keeping the pipe vertical and measure the distance between the surface of the mercury in the bowl and the top of the mercury column inside the tube. d.Take a vertical cylinder of about 20 cm diameter and 1 meter length, bottom end closed and fit a piston to it which does not allow any leakage. Then put a dead weight on top of the piston and measure the distance the piston moves down. e.Fill a glass pipe with mercury and dip a glass pipe into it, while keeping it vertical and pour mercury in it from the top until the height of the column becomes 76 cm.
