How many numbers of \(\mathrm{P}-\mathrm{OH}\) and \(\mathrm{P}-\mathrm{O-P}\) bonds are present in pyrophosphoric acid respectively?

The order and degree of the differential equation \(\left[1+\left[\frac{d y}{d x}\right]^3\right]^{\frac{7}{3}}=7 \frac{d^2 y}{d x^2}\) are respectively.

When tension \(T\) is applied to a sonometer wire of length \(I\), it vibrates with the fundamental frequency \(n\). Keeping the experimental setup same, when the tension is increased by 8 N, the fundamental frequency becomes three times the earlier fundamental frequency \(n\). The initial tension applied to the wire (in newton) was

\(60 \mathrm{~g} \mathrm{~CH}_3 \mathrm{COOH}\) dissolved in \(1 \mathrm{~dm}^3\) solvent, what is molality of solution?

(density = \(1.25 \mathrm{~g} / \mathrm{cm}^3\))

A diatomic gas undergoes adiabatic change. Its pressure \(p\) and temperature \(T\) are related as \(p \propto T^x\), where \(x\) is
