021. The hydrostatic pressure 'P' of a liquid column depends upon the density d', height 'h' of liquid column and also an acceleration 'g' due to
gravity. Using dimensional analysis, the formula for pressure P is
O A. p = hdg
OB. p=h/dg
O c. p=d/hg
O D. p = g/hd

A

Explanation:

hydrostatic pressure, P=hρg,

where 'h' is the ht of the liq column and ρ is the density of the liquid and 'g' is the effective acceleration, but as far as hydroSTATICS is concerned, g stands for the acceleration due to gravity

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
