A mass of `1 kg` attached to the bottom of a spring has a certain frequency of vibration. The following mass has to be added to it in order to reduce the frequency by half :

Ultrasound has frequency of vibration

Ultrasound has -------- frequency of vibration .

A mass m attached to a spring A has a frequency of 3 Hz and a spring B has a frequency of 4 Hz.When both spring are connected as shown in the figure, Find the frequency (in Hz)of oscillation.

A mass m is suspended from a spring of length l and force constant K . The frequency of vibration of the mass is f_(1) . The spring is cut into two equal parts and the same mass is suspended from one of the parts. The new frequency of vibration of mass is f_(2) . Which of the following relations between the frequencies is correct

On suspending a mass m from a spring of force constant k, frequency of vibration f is obtained. If a second spring as shown in the figure, is arranged then the frequency will be :

A mass on the end of a spring undergoes simple harmonic motion with a frequency of 0.5 Hz. If the attached mass is reduced to one quarter of its value, then the new frequency in Hz is
