1. The pressure at a point in a liquid is proportional to the _______ of the liquid and the depth of the point.   gravitational acceleration   force   area   density   Hint Half-n-half Clue   2. One arm of a glass U-tube is open to the atmosphere, whereas the other vertical arm is connected to a gas supply. The difference in levels of mercury (density = 13.6 g cm-3) between the vertical arms of the U-tube manometer is h = 2 cm. If the atmospheric pressure is 760 mm Hg and the gravitational acceleration is 9.8 m s-2, then the pressure of the gas is about   1.061 × 104dynes cm-2   2.666 × 104dynes cm-2   1.016 × 107dynes cm-2   1.040 × 106dynes cm-2   Half-n-half Clue   3. 4 bars = _______ Pascals   4e-05   0.0004   40000   400000   Half-n-half Clue   4.
