Questions Related to resonance
In a forced harmonic oscillator of natural frequency $\omega _0$, the resonant frequency $\omega _r$ is
Resonance is a special case of $\underline{ }$ vibrations, when frequency of the driving force is$\underline{ }$ natural frequency of the body.
A forced oscillator is acted upon by a force $F={ F } _{ \circ }sin\omega t.$. The amplitude of oscillation is given by $\displaystyle\frac{55}{\sqrt{2\omega^2 - 36\omega + 9}}$. The resonant angular frequency is
Imagine a child sitting on a swing in a park and the child's mother is pushing the swing from the back. The mother maintains the same tempo as the motion of the swing. If the mother tries to push at a faster tempo, the arc of the swing will:
A vibrating object will pick out its __________ from a complex excitation and vibrate at those frequencies.
Which one does not work on principles of resonance?
In a resonance column experiment, the first resonance is obtained when the level of the water in tube is $20 cm$ from the open end. Resonance will also be obtained when the water level is at a distance of
Assertion : In the ideal case of zero damping, the amplitude of simple harmonic motion at resonance is infinite.
Reason : All real systems have some damping.
What impulse need to be given to a body of mass $m$, released from the surface of earth along a straight tunnel passsing through centre of earth, at the centre of earth, to bring it to rest(Mass of earth $M$, radius of earth R)
