Find an expression for its fundamental frequency.

Draw a circuit diagram of a transistor amplifier in CE configuration. Find an expression for it’s a.c. current gain.

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]

Find an expression for lateral deviation.

The tension and diameter of a sonometer wire of fundamental frequency n are doubled and density is halved.Its fundamental frequency will be

The length between two bridges of a sonometer wire is L, tension is T and the fundamental frequency is N, if the length between the bridges and tension both are doubled, explain if there is any change in fundamental frequency.

A metal wire of linear mass density of 9.8 gm^-1 is stretched with a tension of 10kg wt between two rigid supports of 1 metre apart. If the wire is allowed to vibrate in its fundamental frequency, then find the frequency of vibration.
