Find the fundamental note emitted by a string of length `10sqrt(10)` cm under tension of 3.14 kg. Radius of string is 0.55 mm and density `=9.8gcm^(-3)`.

What will be the fundamental note emitted by a string of length 20 sqrt(10) cm under a tension of 6.28 kg st if its radius and density are 0.2 mm and 19.6 g//cm^(3) , respectively ?

What is the frequency of the fundamental note emitted by a wire of length 2 m and radius 1 mm under a tension of 200 N. Density of the wire is "1600 kg/m"^3.

the frequency of a note emitted by a silver wire of length 25 cm is 256 when the tension is 10 kg.Calculate the radius of the wire (Density of silver =10.5xx10^(3)kgm^(-3) )

In order to double the frequnecy of the fundamental note emitted by a stratched string the length is reduced to 3/4 th of the original length and the tension is changed. The factor by which the tension is to be changed is

In order to double the frequency of the fundamental note emitted by a stretched string, the length is reduced to (3)/(4) th of the original length and the tension is changed. The factor by which the tension is to be changed is

In order to double the frequency of the fundamental note emitted by a streched string, the length is reduced to 3/4th of the original length and the tension is chaged. The factor by which the tension is to be changed is

The frequency of the note emitted by a silver wire 1 mm in diameter and 50 cm in length is 256 Hz.Find the tension in the wire, if density of silver is 10.5 g cm^(-3) .
