Quiz 2 (solved)A 170 kg rock (density=2700 kg/m3) is dropped into a lake (water density=1000 kg/m3). A man dives in and tries to lift the rock. Determine how much force he needs to apply to lift it from the bottom of the lake.,Consider the cases in Figure b of a solid X in three different fluids A, B, C. Which statement is correct?,The closed end manometer shown below (Figure a) is used to measure the pressure P1. The vapor pressure of the manometer fluid is Pvap. The density of the fluid A is rhoA and that of the manometer fluid is rhoB. Calculate P1 in kPa if rhoA=1.00 g/cm3 rhoB=13.0 g/cm3 Pvap=100.0 kPa, h1=5.00 cm and h2=4.00 cm.,Which one of the following is correct for the figure below (Figure c)?,A solid block (density=660 kg/m3) floats in a fluid with 60% of its volume in the fluid. What is the density of the fluid in kg/m3?
