The volume of an air bubble increases by a factor of 3.65 times as it rises from the bottom of a lake (density = 1000 kg/m "). This is due to the drop of the absolute pressure by a factor of 1/3.65. Ignoring any temperature changes, What is the depth of the lake? Take g = 9.8 m/s . One atmospheric pressure = 1.013 x 105 N/m. Please round your answer to one decimal place.A uniform U-tube is partially filled with water. Oil, of density 0.7 g/cm", is poured into the right arm until the water level in the left arm rises 6.3 cm. What is the length of the oil column? Take the density of water as 1.0 g/cm. Please round your answer to one decimal place. Hint: Gauge pressure of the oil column is equal to the gauge pressure of the water column
