Pressure is a scalar quantity because
A. it is the ratio of force to area and both force and area are vectors.
B. it is the ratio of the magnitude of the force to area.
C. it is the ratio of the component of the force normal to the area.
D. it does not depend on the size of the area chosen.
During calculation of pressure, only the component of force that is normal to the surface is taken into consideration. It is defined as the ratio of magnitude of force normal to the magnitude of the area of the surface.
Hence, pressure is a scalar quantity as it is a ratio of two scalars.

The weight of an empty balloon on a spring balance is W1. The weight becomes W2 when the balloon is filled with air. Let the weight of the air itself be ω. Neglect the thickness of the balloon when it is filled with air. Also neglect the difference in the densities of air inside and outside the balloon.HC Verma - Concepts of Physics Part 1

(a) Pressure decreases as one ascends the atmosphere. If the density of air is ρ, what is the change in pressure dp over a differential height dh?
(b) Considering the pressure p to be proportional to the density, find the pressure p at a height h if the pressure on the surface of the earth is p0.
(c) If p0 = 1.03×105 N m-2, ρ0 = 1.29 kg m-3 and g = 9.8 m s-2, at what height will the pressure drop to (1/10) the value at the surface of the earth?
(d) This model of the atmosphere works for relatively small distances. Identify the underlying assumption that limits the model.

A wooden block of mass 0.5 kg and density 800 kg m-3 is fastened to the free end of a vertical spring of spring constant 50 N m-1 fixed at the bottom. If the entire system is completely immersed in water find (a) the elongation (for compression) of the spring in equilibrium and (b) the time-period of vertical oscillations of the block when it is slightly depressed and released.HC Verma - Concepts of Physics Part 1
In the derivation of P1 - P2 = ρgz, it was assumed that the liquid is incompressible. Why will this equation not be strictly valid for a compressible liquid?HC Verma - Concepts of Physics Part 1
A metal piece of mass 160 g lies in equilibrium inside a glass of water (figure 13-E4). The piece touches the bottom of the glass at a small number of points. If the density of the metal is 8000 kg m4, find the normal force exerted by the bottom of the glass on the metal piece.
