Two particles having position vectors ${\to r}_{1} = (3^i + 5^j) m$ and ${\to r}_{2} = (- 5^i - 3^j) m$ are moving with velocities

$_{1} = (4^i + 3^j) m / s$ and ${\to v}_{2} = (a^i + 7^j) m / s$ .If they collide after 2s, find the value of a.

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?
