Answer» A particle is projected vertically upwards with speed $20 m/s$ from top of a tower of height $20 m$ as shown in figure. Given $B$ is top most point of trajectory and $C$ is at same height as $A$ . List-I gives certain statements regarding particle List - II gives corresponding results in SI units. Match the statements in List-I with corresponding results in List-II. $\begin{matrix} List-I & List-II (I) & ratio of maximum height from ground (BD) & (P) & \frac{1}{\sqrt{2}} to the initial height from ground (AD) is (II) & ratio of distance travelled in 1^{s t} second to & (Q) & 1 the distance travelled in 2^{n d} second is (III) & ratio of initial speed at A to the final & (R) & 2 just before reaching to ground (D) is (IV) & ratio of time taken from A to C and time & (S) & 3 taken from A to B is \end{matrix}$

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?
