At a pressure of 1 atmosphere a column of mercury in a barometer is supported to the height h = 0.76 m. The density of mercury is 13.6 *10³kg/m³. A barometer of similar design filled with water would support a column of water how high at a pressure of 1 atmosphere? A) more than ten times h B) about 1.36h C) less than one tenth h D) the same height h
