Torricelli's barometer used mercury. Pascal duplicated it using French wine of density `984 kg m^(-3)`. Determine the height of the wine column for normal atmospheric pressure.

Explanation

We know that atmospheric pressure, `P=1.01xx10^(5)Pa`
if we use french wine of density `rho=984kgm^(-3)`, then height of wine column should be `h_(m')` such that `P=h rhog`
`impliesh_(m)=(P)/(rhog)=(1.01xx10^(5))/(984xx9.8)=10.47mcong10.5m`
