1.	Two tall buildings are 40 m apart. With what speed a ball must be thrown horizontally from a window 145 m above the ground in one building, so that it will enter a window 22.5 m above the ground in the other ?(Take g=10 m/s2)
Answer» Two tall buildings are $40 m$ apart. With what speed a ball must be thrown horizontally from a window $145 m$ above the ground in one building, so that it will enter a window $22.5 m$ above the ground in the other ? (Take $g = 10 m / s^{2}$ )

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?
