Q1: Pressure exerted by a liquid depends upon its

ANS:B - density

The pressure exerted by a liquid primarily depends on its density and the height of the liquid column. This pressure, often referred to as hydrostatic pressure, is given by the formula: P=ρ⋅g⋅h Where:

• P is the pressure,
• ρ is the density of the liquid,
• g is the acceleration due to gravity, and
• ℎ is the height of the liquid column.

Surface tension, viscosity, and buoyancy also play important roles in the behavior of liquids, but they do not directly determine the pressure exerted by the liquid. Surface tension is a measure of the cohesive forces between molecules at the surface of a liquid, viscosity is a measure of a liquid's resistance to flow, and buoyancy is the upward force exerted on an object submerged in a fluid due to the difference in pressure between the top and bottom of the object.
