A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.

What is the acceleration of the block and trolley system show n in a figure, if the coefficient of kinetic friction betw een the trolley and the surface is 0.04 ? What is the tension in the string ? (Take g = 10 ms^(2) ). Neglect the mass of the string.

Newton's laws of motion can be applied to a block in liquid also force due to liquid (e.g. upthrust) are also considered in addition to toher forces. A small block of weight W is kept inside. The block is attached with a string connected to the bottom of the vessel. Tension in the string is W//2 Q. If weight of the block is doubled then tension in the string becomes x times and the time calculated above becomes y times then

Prove that the tension throughout the string is uniform when the mass of string is considered to be zero.
