1.	A layer of ice at 0∘C of thickness x1 is floating on a surface of water. L,ρ and K respectively are the latent heat of fusion of ice, density of ice and thermal conductivity of ice. If the atmospheric temperature is −T∘C, the time taken for the thickeness of the layer of ice to increase from x1 to x2 is given by
Answer» A layer of ice at $0^{\circ} C$ of thickness $x_{1}$ is floating on a surface of water. $L, ρ$ and $K$ respectively are the latent heat of fusion of ice, density of ice and thermal conductivity of ice. If the atmospheric temperature is $- T^{\circ} C$ , the time taken for the thickeness of the layer of ice to increase from $x_{1}$ to $x_{2}$ is given by

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?
