The density of mercury is 13.5 times greater than the density of water. if you were to build a barometer that used water instead of mercury to record the standard pressure at sea level, what would be the height of that barometer? assume that the mercury barometer is 76 centimeters, or 29.92 inches, long (this is the standard atmospheric pressure at sea level.

Height of water column 10.26 m

Explanation:

Given data;

Mercury density is 13.5 times higher than water density.

Mercury barometer 76 cm or 29.92 inches

we know that the mercury column is balanced by the pressure of air  in mercury barometer

we know also standard atmospheric is equivalent to 29.92 inches of mercury

Height of water column must be

b.

developed countries have tended to improve the environment, while developing countries have tended to damage it.
