In a lab, a foot-long test tube contains gasoline (density equal to 748.9 kg/m³) and oil (density equal to 950 kg/m3). The gasoline occupies the upper half of the tube while the oil occupies the lower half of the test tube. Compute for the pressure at the bottom of the tube.A: 1950.2 N/m^2B: 118.5 N/m^2C: 890.4 N/m^2D: 2537.3 N/m^2E: none of the above

< The mass of a piece of ice is 0.850 kg. density of water = 1.00 x 103 kg/m³, and density of ice = 917 kg/m³. 2. What is the buoyant force on the ice floating freely in liquid water? Enter a positive answer if the buoyant force is upward and a negative answer if the buoyant force is downward. N Question 2 (of 8)

A very simple way of measuring the depth of a fluid in a gas station's underground gasoline tank is by using a pressure gauge that measures gauge pressure. Assume the fluid in the tank is gasoline with a density of 700 kg/m3 and g = 9.80 m/s2. If the gauge pressure is 25.9 kPa what is the depth of the gasoline in the tank? Assume 3 significant digits. Watch the units!   A. 3.78 cm   B. 37.8 m   C. 0.378 m   D. 3.78 m   E. 3.78 mm
