$\frac{{dy}}{{dt}}\,\, = \,2\,\omega \sin \,(\omega t\, + \,\,{\theta _0})\,$ સમીકરણમાં ${\text{( }}\omega {\text{t + }}{\theta _{\text{0}}}{\text{ )}}$ ના પરિમાણ.......છે
A
$M^{1}L^{1}T^{1}$
B
$M^{1}L^{1}T0$
C
$M^{1}L^0T^0$
D
$M^0L^0T^0$
Solution
The given ralation is:
$\frac{d y}{d t}=2 w \sin \left(w t+\phi_0\right)$
It is the equation for the velocity of the wave.
Arguments of trignometric functions are dimension less $\Rightarrow( wt +\phi)$ has dimension $\left[ M ^0 L ^0 T ^0\right]$.
