SECTION C
III. LAQ: Answer any TWO of the following questions. 2 x 8 = 16 M - Explain the formation of stationary waves in an air column enclosed in open pipe. Derive the equations for the frequencies of the harmonics produced. A open organ pipe 85 cm long is sounded. If the velocity of sound is 340 m/s, what is the fundamental frequency of vibration of the air column?
- State the working principle of potentiometer. Explain with help of circuit diagram how the emf of two primary cells are compared by using potentiometer. A potentiometer wire is 5m long and a potential difference of 6V is maintained between its ends. Find the emf of a cell
which balances against a length of 180 cm of the potentiometer wire. - What is radioactivity? State the law of radioactive decay. Show that radioactive decay is exponential in nature. The half life of radium is 1600 years. How much time does 1g of radium take to reduce to 0.125g?
