Practice CBSE Class 11 Oscillations in the app →A pendulum bob oscillates as $x(t) = 0.05\cos(2\pi t)$ in metres. Its amplitude and period are:A spring of constant $k = 100$ N/m carries a mass of $1$ kg. Its period of oscillation is:A simple pendulum's length is increased four times. Its period changes by a factor of:A child's swing is pushed gently at its natural frequency and the amplitude grows large. This phenomenon is caMotion that repeats to and fro about a mean position is called:Which instrument is given as having vibrating strings?The simplest form of oscillatory motion is called:In simple harmonic motion the force is proportional to the:The mean position in an oscillation is also the:The smallest interval after which motion repeats is the:The SI unit of the period of oscillation is the:The number of repetitions per unit time is called the:The unit of frequency is named the:One hertz equals how many oscillations per second?Must the frequency of an oscillation be a whole number?For an oscillating pendulum, what serves as the displacement?In simple harmonic motion, the speed is maximum where displacement is:In simple harmonic motion, the speed at the extremes is:In the standard equation, the symbol A stands for the:The time-dependent quantity in the cosine argument is the:The value of the phase at time zero is called the phase:The force in simple harmonic motion always points towards the:Because it pulls the body back, the force in SHM is called:
