The sound of explosion on a ship located 10km away from the beach was heard 28.6 seconds after the explosion was seen. Estimate the temperature of air at that time.
- A. 31 C
- B. 31 K
- C. 26.2 C
- D. 288.5 K
Answer: A. 31 C
Explanation: c = 10000/28.6 = 349.65 m/s. c = $\sqrt{1.4 * 287 * T}$. T = 304 K = 31 C.
