1.	A swimmer can swim with a speed v in still waterIf the swimmer crosses a swimming pool of width ′d′ from A to directly opposite point B on other side in time t1 as shown in figure and in a flowing river (river velocity u) of same width ′d′ from A′ to directly opposite point B′ on other bank in time t2, then (t1t2) is equal to: (Assume v>u)
Answer» A swimmer can swim with a speed $v$ in still water If the swimmer crosses a swimming pool of width $^{'} d^{'}$ from $A$ to directly opposite point $B$ on other side in time $t_{1}$ as shown in figure and in a flowing river (river velocity $u$ ) of same width $^{'} d^{'}$ from $A^{'}$ to directly opposite point $B^{'}$ on other bank in time $t_{2}$ , then $(\frac{t_{1}}{t_{2}})$ is equal to: (Assume $v > u$ )

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?
