    The air pressure is 9.8 * 10^4 pa

    The water will rise to a height of 10.0 meter

    Explanation:

    Step 1: Data given

    As a storm from moves in, you notice that a column of mercury in a barometer rises to 736 mm.

    Step 2: Calculate the air pressure

    The Pressure against the mercury column = h*d*g = 0.736 * 13593 * 9.81 = 9.8 * 10^4 Pa

    Step 3: Calculate the height of the water

    Let the Pressure the water column for same pressure is h meter : -

    9.8 * 10^4 = h*d*g

    =>9.8*10^4 = h*1000*9.81

    =>h = 10.0 meter

    The water will rise to a height of 10.0 meter
