There is some change in length when a 33000 N tensile force is applied on a steel rod of area of cross section 10−3 m2. The change of temperature required to produce the same elongation, if steel rod is heated, is: (The modulus of elasticity is 3×1011 N/m2 and the coefficient of linear expansion of steel is 1.1×10−5∘C−1)

1.	There is some change in length when a 33000 N tensile force is applied on a steel rod of area of cross section 10−3 m2. The change of temperature required to produce the same elongation, if steel rod is heated, is: (The modulus of elasticity is 3×1011 N/m2 and the coefficient of linear expansion of steel is 1.1×10−5∘C−1)
Answer» There is some change in length when a $33000 N$ tensile force is applied on a steel rod of area of cross section $10^{- 3} m^{2}$ . The change of temperature required to produce the same elongation, if steel rod is heated, is: (The modulus of elasticity is $3 \times 10^{11} {N/m}^{2}$ and the coefficient of linear expansion of steel is $1.1 \times {10^{- 5}}^{\circ} C^{- 1}$ )

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?
