Answer : 3. "Thunder"
Explanation :
Answer: C) Thunder Explanation: The Sound Following the flash of lighting is because of Thunder. Lightning is seen earlier than thunder because light travels much faster than sound. The roar of thunder is the result of a shock wave produced when lightning super-heats the air through which it passes, causing that air to expand very rapidly. This rapid expansion of air creates a shock wave that travels outward at close to the speed of sound.

Answer :
Explanation :
1. How to find Speed(s) if distance(d) & time(t) is given: Speed (S) = Distance (D)Time (T) Ex: Find speed if a person travels 4 kms in 2 hrs? Speed = D/T = 4/2 = 2 kmph. 2. Similarly, we can find distance (d) if speed (s) & time (t) is given by Distance (D) = Speed (S) x Time (T) Ex : Find distance if a person with a speed of 2 kmph in 2 hrs? Distance D = S X T = 2 x 2 = 4 kms. 3. Similarly, we can find time (t) if speed (s) & distance (d) is given by Time (T) = Distance (D)Speed (S) Ex : Find in what time a person travels 4 kms with a speed of 2 kmph? Time T = D/S = 4/2 = 2 hrs. 4. How to convert km/hr into m/sec : P km/hr = P x 518 m/sec Ex : Convert 36 kmph into m/sec? 36 kmph = 36 x 5/18 = 10 m/sec 5. How to convert m/sec into km/hr : P m/sec = P x 185 kmph. Ex : Convert 10 m/sec into km/hr? 10 m/sec = 10 x 18/5 = 36 kmph. 6. If the ratio of the speeds of A and B is a:b, then the ratio of the times taken by them to cover the same distance is b : a. 7. Suppose a man covers a certain distance at x km/ hr and an equal distance at y km/hr . Then, the average speed during the whole journey is 2xyx+y km/hr.
