The ideal gas equation is formulated as: PV = nRT. In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the total amount of ideal gas that is measured in terms of moles, R is the universal gas constant, and T is the temperature

Let us consider a liquid of density ρ in a vessel as shown in figure. Let us find the pressure difference between two points A and B separated by vertical height h.

To evaluate the pressure difference between A and B, consider an imaginary cubiod of area of cross-section a of liquid with upper and lower cap passing through A and B respectively. The volume of the imaginary cylinder is,.

V=ah

Mass of liquid of imaginary cylinder is,

m = ρah

Let P1 and P2 be the pressure on the upper and lower face of cylinder. The different forces acting on the imaginary cylinder are:

(i) weight mg = ρahg in vertically downward direction.

(ii) Downward thrust of F1 =P1a on upper cap.

(iii) Upward thrust of F2 = P2a on lower face. As the imaginary cylinder in the liquid is in equilibrium, therefore the net force on the cylinder is zero, i.e.

Thus the pressure difference between two points separated vertically by height h in the presence of gravity is ρgh. In the absence of gravity this pressure difference becomes zero.

Electric Current is the flow of electrons. But an electric Circuit is the closed path in which electric current flows.

• When an electric current flows through a wire, the wire gets heated. It is the heating effect of current or When current flows through a metal wire it gets heated up, this is called heating effect of current. E.g. a glowing electric bulb becomes warm. This effect has many applications like Electric Heater, Light Bulb etc.
• When an electric current flows through a wire, it produces magnetic effect around it. A current carrying coil of an insulated wire wrapped around a piece of iron is called an electromagnet. Magnetic Effect of electric current has many applications like Electric Bell, Motor, Fan etc

Force=Mass×Acceleration unit of force=kg×(m/s^2) =kgms^-1 Dimensional formula of force=MLT^-1

Meena Khandelwal 3 years, 3 months ago

Acceleration=change in velocity/time =L/T/T =L/Tsquare Force=Mass×Acceleration =M×L/T square =ML/Tsquare it is dimensional formula of force.

Change of velocity with respect to time. a = velocity/time

Sonali Maurya 3 years, 4 months ago

the rate of change of velocity is called acceleration. a= velocity/ time.

Yogita Ingle 3 years, 5 months ago

Acceleration is rate of change of velocity with time. It is denoted by ‘a’ and the SI unit is m/s2.
