1.	A rod is measured at 10∘C using a scale calibrated at that temperature. Find the percentage error in length, if thermal coefficients of linear expansion of the rod and scale are 3×10−5/∘C and 2×10−5/∘C respectively, and the rod is measured at 50∘C.
Answer» A rod is measured at $10^{\circ} C$ using a scale calibrated at that temperature. Find the percentage error in length, if thermal coefficients of linear expansion of the rod and scale are $3 \times 10^{- 5} /^{\circ} C$ and $2 \times 10^{- 5} /^{\circ} C$ respectively, and the rod is measured at $50^{\circ} C$ .

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
