A spring has a mass m suspended from it. If the spring is cut in half and same mass is suspended, from one of the halves, will the frequency of vibration is changed ?

A spring is cut into two equal halves. How is spring constant of each half affected?

A spring balance is graduated from O to 16 kg. When is reads 16 kg the spring is stretched by 10 cm. A body suspended from the spring is found to oscillate vertically with a frequency 2 oscillations per second. What the weight of the body ?

A spring having a spring constant K is loaded with mass m. The spring is in two equal parts and one of them is loaded with the same mass. The new spring constant is

Two springs are connected in parallel as shown. If the mass is displaced from its equilibrium position and released. What is the resultant frequency of vibration?

When a certain weight is suspended to a long uniform wire its length increases by one cm. If the same weight is suspended to another wire of the same material and length but having a diameter half of the first one, the increase in its length will be

A string 25 cm long and having a mass of 2.5 g is under tension.When the string is vibrating in its first overtone and air in a 40 cm long closed pipe in its fundamental frequency 8 beats per second are heard.it is observed that decreasing the tension in the string decreases the beat frequency.Find the tension in the string.[Velocity of sound is 320 m/s]

A sonometer wire is under tension of 40 N and the length between the two bridges is 60 cm.A one metre long wire of the sonometer has a mass of 1.0 g.Deduce the speed of transverse waves and the frequency of the second harmonic.

A simple pendulum of length I and mass m is suspended in a car that is travelling with a constant speed v around a circle of radius R. If the pendulum undergoes small oscillations about its equilibrium position, what will be its frequency•of oscillation ?
