✓
$M{L^{ - 1}}{T^{ - 2}}$
D
$ML{T^{ - 2}}$

✓

Answer

Correct option: C.

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

c
(c) Shear modulus = $\frac{{{\rm{Shearing\, stress}}}}{{{\rm{Shearing\, strain }}}}$ $ = \frac{F}{{A\theta }} $ $= [M{L^{ - 1}}{T^{ - 2}}]$

A cubic metal block of mass $5 \,kg$ and edge length $0.1 \,m$ and at an initial temperature of $100^{\circ} C$ is placed on a thermally insulating flat surface and exposed to air at $0^{\circ} C$. The time in seconds required to cool the block to a temperature of $37^{\circ} C$ is closest to

(Note: Specific heat of the metal $=500 \,J / kg /{ }^{\circ} C$; Heat transfer coefficient from block to air $=50 \,W / m ^2 /{ }^{\circ} C$ )

The temperature of an ideal gas is increased from $200\,K$ to $800\,K$. If r.m.s. speed of gas at $200\,K$ is $v_0$. Then, r.m.s. speed of the gas at $800\,K$ will be:

A block is moving on an inclined plane making an angle $45^{\circ}$ with the horizontal and the coefficient of friction is $\mu$. The force required to just push it up the inclined plane is $3$ times the force required to just prevent it from sliding down. If we define $N=10 \ \mu$, then $N$ is

The potential energy $(U)$ of a diatomic molecule is a function dependent on $r$ (interatomic distance) as

$U =\frac{\alpha}{ r ^{10}}-\frac{\beta}{ r ^{5}}-3$

where, $\alpha$ and $\beta$ are positive constants. The equilibrium distance between two atoms will be $\left(\frac{2 \alpha}{\beta}\right)^{\frac{a}{b}},$ where a $=$ ..........

A particle of mass $m$ slides from rest down a plane inclined at $30^o$ to the horizontal. The force of resistance acting on the particle during motion is $ms^2$ where $s$ is the displacement of the particle from its initial position. The velocity (in $m/s$) of the particle when $s = 1\,m$ is $v$. The value of $\frac{3v^2}{14}$ is :-

Each of the two strings of length $51.6\,\, cm$ and $49.1\,\, cm$ are tensioned separately by $20\,\, N$ force. Mass per unit length of both the strings is same and equal to $1\,\, g/m.$ When both the strings vibrate simultaneously the number of beats is
