If the tension in a sonometer wire is increased by 2.5 N,its frequency increases in the ratio 3:2.What was the original tension?

If the tension of the wire is increased four times and its length reduced to half the original length the frequency of vibration

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.

Word Problem on Fraction The sum of the numerator and denominator of a fraction is 4 more than twice the numerator and if the numerator and denominator are increased by 3 they are in the ratio 2 : 3 . Find the fraction.

The radii of the bases of a cylinder and a cone are in the ratio 3:4 and their heights are in the ratio 2:3.What is the ratio of their volumes?

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

A sonometer wire emits a note of frequency 150 Hz.What will be the frequency of the note emitted by it if its tension increaeed in the ratio 9:16 and the length is doubled?

A tuning fork has got a frequency equal to the fundamental frequency of 25 cm length of a sonometer wire.Without change the load,if the legth of the wire is increased to 25.5 cm then 3 beats are heard per secondwhen the fork and wire are made to vibrate together.Calculate frequency of the tuning fork.

Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method:The area of rectangle gets reduced by 9 square units,if its length is reduced by 5 units and breadth is increased by 3 units.If we increase the length by 3 units and the breadth by 2 units,the ares increases by 67 square units.Find the dimensions of the rectangle.

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]
