How do you find the dimensional formula of viscosity?
How do you find the dimensional formula of viscosity?
Or, η = [M L T-2] × [L] × [L2]-1 × [L1 T-1]-1 = [M1 L-1 T-1]. Therefore, the Coefficient of Viscosity is dimensionally represented as [M1 L-1 T-1].
What is the dimensional formula of velocity?
Therefore, velocity is dimensionally represented as [M0 L1 T-1].
What is dimensional formula of pressure?
Or, P = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2. Therefore, the pressure is dimensionally represented as M1 L-1 T -2.
What is the dimensional formula of action?
Action has the dimensions of [energy]⋅[time], and its SI unit is joule-second, which is identical to the unit of angular momentum.
What is the physical quantity whose dimensions are ML2T 2?
The Dimension of moment is [ML2T-2] which is same as the energy, however there is no direct relationship between the two.. The SI unit of moment is (NM). Similarly, the dimension formula for work is also [ML2T-2]…….
What is the product of energy and time?

What are the dimensions of electrical resistance?
Electric resistance has the dimension length squared mass per time cubed electric current squared. The SI derived unit of electric resistance is the ohm, which is defined as a volt per ampere.
What is dimensional formula of resistivity?
D. [ML2T−2A−3] Hint: First we have to know what resistivity is: Resistivity is an electrical opposition of a conductor of unit cross-sectional area and unit length.
What is the dimensional formula of specific resistance?
[ML−2A−1]
What is SI unit of specific resistance?
The metric unit for specific resistance is the ohm-meter (Ω-m), or ohm-centimeter (Ω-cm), with 1.66243 x 10-9 Ω-meters per Ω-cmil/ft (1.66243 x 10-7 Ω-cm per Ω-cmil/ft).
What is the relationship between resistance and current?
The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
What is voltage resistance and current?
Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).
