Dimensional formula $M L^{2} T^{- 3}$ represents

Force

Power

Energy

Work

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Power $= \frac{Work}{Time} = \frac{M L^{2} T^{- 2}}{T} = M L^{2} T^{- 3}$

● ● ● ● ●

The dimensions of calorie are

$M L^{2} T^{- 2}$

$M L T^{- 2}$

$M L^{2} T^{- 1}$

$M L^{2} T^{- 3}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Calorie is the unit of heat i.e., energy.

So dimensions of energy $= M L^{2} T^{- 2}$

● ● ● ● ●

If L and R are respectively the inductance and resistance, then the dimensions of $\frac{L}{R}$ will be

[Only for Dropper and XII batch]

$M^{0} L^{0} T^{- 1}$

$M^{0} L T^{0}$

$M^{0} L^{0} T$

Cannot be represented in terms of M, L and T

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

$V = \frac{L i}{t} L = \frac{V t}{i} R = \frac{V}{i} T h e n, \frac{L}{R} = \frac{\frac{V t}{i}}{\frac{V}{i}} = t$

$\frac{L}{R}$ = Time constant

● ● ● ● ●

Which pair has the same dimensions

Work and power

Density and relative density

Momentum and impulse

Stress and strain

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Impulse = change in momentum so dimensions of both quantities will be same and equal to MLT^–1

● ● ● ● ●

If C and R represent capacitance and resistance respectively, then the dimensions of RC are

[Only for droppers]

$M^{0} L^{0} T^{2}$

$M^{0} L^{0} T$

$M L^{- 1}$

None of the above

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

$R C = T$

âˆµ $[R] = [M L^{2} T^{- 3} I^{- 2}]$ and $[C] = [M^{- 1} L^{- 2} T^{4} I^{2}]$

● ● ● ● ●

Dimensions of one or more pairs are same. Identify the pairs

Torque and work

Angular momentum and work

Energy and Young's modulus

Year and wavelength

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

[Torque] = [work] = [ML²T^–2]

● ● ● ● ●

Dimensional formula for volume elasticity is

$M^{1} L^{- 2} T^{- 2}$

$M^{1} L^{- 3} T^{- 2}$

$M^{1} L^{2} T^{- 2}$

$M^{1} L^{- 1} T^{- 2}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Volume elasticity = $\frac{Force/Area}{Volume strain}$

Strain is dimensionless, so

[Elasticity] = [Stress]

● ● ● ● ●

The dimensions of universal gravitational constant are

$M^{- 2} L^{2} T^{- 2}$

$M^{- 1} L^{3} T^{- 2}$

$M L^{- 1} T^{- 2}$

$M L^{2} T^{- 2}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

$F = \frac{G m_{1} m_{2}}{d^{2}} \Rightarrow G = \frac{F d^{2}}{m_{1} m_{2}}$

$∴ [G] = \frac{[M L T^{- 2}] [L^{2}]}{[M^{2}]} = [M^{- 1} L^{3} T^{- 2}]$

● ● ● ● ●

The dimensional formula of angular velocity is

$M^{0} L^{0} T^{- 1}$

$M L T^{- 1}$

$M^{0} L^{0} T^{1}$

$M L^{0} T^{- 2}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Angular velocity = $\frac{θ}{t},$ $[ω] = \frac{[M^{0} L^{0} T^{0}]}{[T]} = [T^{- 1}]$

● ● ● ● ●

The dimensions of power are

$M^{1} L^{2} T^{- 3}$

$M^{2} L^{1} T^{- 2}$

$M^{1} L^{2} T^{- 1}$

$M^{1} L^{1} T^{- 2}$

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Power = $\frac{Work done}{Time} = [\frac{M L^{2} T^{- 2}}{T}] = [M L^{2} T^{- 3}]$
