Question

If water be used to construct a barometer, what would be the height of water column at a standard atmospheric presure (76cm of mercury)?

Answer 1

Correct Answer - A::C
Standard atmospheric pressure is always pressure exerted by 76 cm.
`Hg column =76xx13.6xxg` Dyne/cm^2, if water is used in the barometer
`Let h is the height of water column
`:. hxxrho_wxxg=76xx13.6xxg`
` rarr h=(76xx13.6)/`
`=1033.6cm
