- 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…Use the worked example above to help you solve this problem. An airplane has wings, each with area 4.15 m2, designed so that air flows over the top of the wing at 246 m/s and underneath the wing at 221 m/s. Find the mass of the airplane such that the lift on the plane will support its weight, assuming the force from the pressure difference across the wings is directed straight upwards. Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" and the total mass of the craft is 350 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of gravity on the surface of Mars is about 3.8 m/s2.Consider an air compressor operating steadily. How would you compare the volume flow rates of the air at the compressor inlet and exit?
