QUESTION 1 When you are swimming at the bottom of a pool, the water above and around you exerts force on your eardrunm. Calculate the force (in N) exerted on your eardrum when you are at the bottom of a pool that is 5.0 m deep. Assume that the area of your eardrum is 1 cm^2 and the density of water is 1000 kg/m^3 (10.000 cm^2 = 1m^2) (Ans: 5N) To solve this, which of the followving equation/s should you use (check as many that best applies) O du = dQ - dW or AU= Q - W O P= pgh 1 4192| F = 4περ O Q= MCAT F P= Op =m/V W = dv P2+pgh2+ O Tk= T+273.15K O F=ma O Fo=P fluiagV submerged O PV = nRT O F1 F2
