Here are the answers to question 4: a) (i) Using a letter on the diagram, state where she places her mouth. The student places her mouth at position P. a) (ii) Explain why the displacement occurs. When the student sucks at position P, the air pressure above the water column on that side is reduced. The higher atmospheric pressure acting on the water surface at position R then pushes the water down on the R side and up on the P side, causing the observed displacement. b) Determine the pressure difference caused by the sucking. Step 1: Identify the given values and the height difference. Density of water, = 1000 kg/m^3 Acceleration due to gravity, g = 10 m/s^2 (standard approximation) Height of water on the left side = 10 cm Height of water on the right side = 13 cm The difference in height, h, is the difference between the two water levels: h = 13 cm - 10 cm = 3 cm Step 2: Convert the height difference to meters. h = 3 cm = 0.03 m Step 3: Calculate the pressure difference using the formula P = g h. P = 1000 kg/m^3 × 10 m/s^2 × 0.03 m P = 300 Pa The pressure difference caused by the sucking is 300 Pa. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
