The determination of the value of acceleration due to gravity ($g$) by simple pendulum method employs the formula, $g = 4\pi^2 \frac{L}{T^2}$. The expression for the relative error in the value of $g$ is:
The truth table for the given logic circuit is:
If $x = at + bt^2$, where $x$ is the distance travelled by the body in kilometres while $t$ is the time in seconds, then the units of $b$ are
Pick the wrong answer in the context with rainbow.
Which relation is wrong?
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:
Two planets orbit a star in circular paths with radii $R$ and $4R$, respectively. At a specific time, the two planets and the star are aligned in a straight line. If the orbital period of the planet closest to the star is $T$, what is the minimum time after which the star and the planets will again be aligned in a straight line (at the initial position)?
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:
The dimensional formula of relative density is:
Which two of the following five physical parameters have the same dimensions? (1) energy density (2) refractive index (3) dielectric constant (4) Young's modulus (5) magnetic field
