Anormal blood pressure reading is less than 120/80 where both numbers are gauge pressures measured in millimeters of mercury (mmhg). what are the absolute and gauge pressures in pascals at the base of a 0.0930 m column of mercury? (the density of mercury is rhohg = 13.6 ✕ 103 kg/m3. assume the system is at sea level.)

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
