Question:medium

When two sound waves having amplitudes 3 and 5 units are superimposed, find the ratio of maximum to minimum intensity of the resultant wave.

Show Hint

This is a standard CET problem. Remember the shortcut: Ratio \(= \left( \frac{a_1 + a_2}{a_1 - a_2} \right)^2\). For \(3\) and \(5\), the sum is \(8\) and difference is \(2\). \(8/2 = 4\), and \(4^2 = 16\). Result is \(16:1\).

Find the heat energy that must be supplied to 14 g of nitrogen at room temperature to raise its temperature by \(48^\circ\text{C}\) at constant pressure. (Molecular weight of nitrogen = 28; \(R\) is the gas constant; \(C_p = \frac{7}{2}R\) for a diatomic gas.)
