If the dimension of a physical quantity are given by $M^a L^b T^c$, then the physical quantity will be
A rectangular film of liquid is extended from $(4 \text{ cm} \times 2 \text{ cm})$ to $(5 \text{ cm} \times 4 \text{ cm})$. If the work done is $3 \times 10^{-4} \text{ J}$, then the value of the surface tension of the liquid is:
The surface tension of a liquid is $70\text{ dyne/cm}$. In MKS system its value is
The length, breadth, and thickness of a block are given by $l = 12\text{ cm}$, $b = 6\text{ cm}$ and $t = 2.45\text{ cm}$. The volume of the block according to the idea of significant figures should be:
If the error in the measurement of the radius of a sphere is $2\%$, then the error in the determination of the volume of the sphere will be:
A particle is released from a height $S$ above the surface of the earth. At a certain height, its kinetic energy is three times its potential energy. The height from the earth's surface and the speed of the particle at that instant are respectively:
