The sound from a very high burst of fireworks takes 5 s to arrive at the observer. The burst occurs 1662 m above the observer and travels vertically through two stratifier layers of air, the top one of thicknessd1 at 0∘C and the bottom one of thickness d2 at 20∘C. Then (assume velocity of sound at 0∘C is 330 m/s)

1.	The sound from a very high burst of fireworks takes 5 s to arrive at the observer. The burst occurs 1662 m above the observer and travels vertically through two stratifier layers of air, the top one of thicknessd1 at 0∘C and the bottom one of thickness d2 at 20∘C. Then (assume velocity of sound at 0∘C is 330 m/s)
Answer» The sound from a very high burst of fireworks takes 5 s to arrive at the observer. The burst occurs 1662 m above the observer and travels vertically through two stratifier layers of air, the top one of thickness $d_{1}$ at $0^{\circ} C$ and the bottom one of thickness $d_{2}$ at $20^{\circ} C$ . Then (assume velocity of sound at $0^{\circ} C$ is 330 m/s)
