To solve the question, we need to analyze the behavior of the oscillating air element as it moves through the point of zero displacement in a longitudinal wave. Here’s the step-by-step solution: ### Step 1: Understand the Nature of Longitudinal Waves Longitudinal waves, such as sound waves, involve oscillations of particles in the medium parallel to the direction of wave propagation. As the wave travels, particles of the medium move back and forth around their equilibrium positions. **Hint:** Recall that in longitudinal waves, particle motion is parallel to wave direction. ### Step 2: Identify the Point of Zero Displacement ...

If a system at equilibrium is subjected to a change of any one of the factors such as concentration , pressure or temperature, the system adjusts itself in such a way so as to minimise the effect of that change. Effect of change in concentration on equilibrium: As we add or remove reactant (or product) the ratio of equilibrium concentratio become 'Q' (reaction quotient) and depending upon. QltK : equilibrium will shift ihn forward direction QgtK equilibrium will shift in backward direction Effect of change in pressure : If a system in equilibrium consists of gases, then the concentrations of all the components can be altered by changing the pressure. When the pressure on the system is increased, then equilibrium will shift in the direction in which there is decrease in number of moles i.e., towards the direction in which there is decrease in volume. Effect of change in pressure on melting point : There are two rypes of solids : Solids whose volume decreases on melting, e.g., ice, diamond, carborundum, magnesium nitride and quartz. Solid (higher volume) hArr Liquid (higher volume) The process of melting is facillitated at high pressure, thus melting point is lowered. Solid whose volume increase on melting, e.g., Fe, Cu, Ag, Au, etc. Solid (lower volume) hArr Liquid (higher volume) In this case the process of melring becomes difficult at high pressure, thuse melting point becomes high. Solubility of substances : When solid substance are dissolved in water, either heat is evolved. for endothermic solubility process solubility increase with increase in temperature. For exothemic solubility decrease with increase in temperature. Solubility of gases in liquids : when a gas dissolves in liquid, there is decreases in voolume. Thus increase of pressure will faavour the dissolution of gas in liquid.

Which of the following is wrong regarding Searle's apparatus method in finding Young's modulus of a given wire? (a) Average elongation of wire will be determined with a particular load while increasing the load and decreasing the load. (b) Reference wire will be just taut and experimental wire will undergo foe elongation. ( c) Air bubble in the spirit level will be disturbed from the central position due to relative displacement between the wires due to elongation. (d) Average elongation of the wires is to be determined by increasing the load attached to both the wires.
