v_100_string_diff_newFlow

In an experiment , it was found that a string vibrated in 5 loops when 100gm was placed in the pan. What must be placed in the pan to make the string vibrate in 10 loops ?

A string length 1m is fixed at one end with a bob of mass 100g and the string makes ((2)/(pi))revs^(-1) around a vertical axis through a fixed point. The angle of inclination of the string with nvertical is

Two strings of the same material and the same area of cross-section are used in an wxperiment. One is loaded with 12 kg and the other with 3 kg The fundamental fequency of the first string is equal to the first overtone of the second string. If the length of the second string is 100 cm, then the length of the first string is

Speed of transverse wave on string is v . If tension is increased by factor of 4 and radius of the string is increased by factor of 2, then the new wave speed will be :

A 100 Omega iron is connected to 220 V, 50 wall plug. What is (i) peak pot. Diff. (ii) average pot.diff. over half cycle (iii) rms current ?

The frequency of vibration (v) of a string may depend upon length (I) of the string, tension (T) in the string and mass per unit length (m) of the string. Using the method of dimensions, derive the formula for v.
