Plz 20 pt question 1 the block in the illustration is floating in water, which ahs a density of 1.0 g/cm^3. about 40% of the block is below water. what is the estimated density of the block? question 1 options: 0.60 g/cm^3 0.90 g/cm^3 0.40 g/cm^3 1.0 g/cm^3 question 2 what is the upward force that makes things float? question 2 options: resistance density buoyancy gravity question 3 according to pascal's principle, pressure through a fluid is question 3 options: random unmoving rigid uniform question 4 how does a wing achieve lift? question 4 options: by moving air at the same rate on the top and the bottom of the wing by forcing air to move slower over the top of the wing by forcing air to move faster over the top of the wing question 5 pressure is measured as question 5 options: force per unit area force per gram force per inch force divided by mass question 6 (1 point) question 6 unsaved if the amount of a gas in a sealed container increases, what happens to the pressure in the container? question 6 options: the pressure decreases the pressure increases the pressure stays the same
