A source of sound is moving towards a stationary observer with $\left(\frac{1}{10}\right)^{\text{th}}$ the speed of sound. The ratio of apparent to real frequency is

Equation of simple harmonic progressive wave is given by $y=\frac{1}{\sqrt{a}}\sin(\omega t)\pm \frac{1}{\sqrt{b}}\cos(\omega t)$. Then the resultant amplitude of the wave is ($\cos 90^{\circ}=0$):

The power factor of an R-L circuit is $\frac{1}{\sqrt{2}}$. If the frequency of AC is doubled the power factor will now be

In an AC circuit, the current is $i=5 \sin(100t - \frac{\pi}{2})$ A and voltage is $e=200 \sin(100t)$ volt. Power consumption in the circuit is ($\cos 90^{\circ}=0$)

A closed organ pipe of length $L_{1}$ and an open organ pipe contain diatomic gases of densities $\rho_{1}$ and $\rho_{2}$ respectively. The compressibilities of the gases are same in both pipes, which are vibrating in their first overtone with same frequency. The length of the open organ pipe is (Neglect end correction)
