Question

Звук распространяется за 5 с на расстояние 1.7км.1)на какое расстояние распространяется звук за 2с 2)через сколько секунд слышен шум грома на расстоянии2.72 км

Answer 1

1)

5с ==== 1,7 км

2с ==== Х

х=2*1,7/5=0,68км. 

2)

5с ==== 1,7км

Хс ==== 2,72км

х=5*2,72/1,7=8 с 

Ответ. 0,68 км, 8 сек

Answer 2

Sound Propagation Distance

Sound travels through a medium, such as air, at a certain speed. In general, the speed of sound in dry air at room temperature is approximately 343 meters per second (m/s) or 1235 kilometers per hour (km/h) [[1]].

1) Distance traveled by sound in 2 seconds: To calculate the distance traveled by sound in 2 seconds, we can use the formula: Distance = Speed × Time

Given that the speed of sound is approximately 343 m/s, we can calculate the distance as follows: Distance = 343 m/s × 2 s = 686 meters (m)

Therefore, sound would travel approximately 686 meters in 2 seconds [[1]].

2) Time taken for the sound of thunder to be heard at a distance of 2.72 km: To calculate the time taken for the sound of thunder to be heard at a certain distance, we can use the formula: Time = Distance / Speed

Given that the distance is 2.72 km and the speed of sound is approximately 343 m/s, we need to convert the distance to meters: Distance = 2.72 km × 1000 m/km = 2720 meters (m)

Now we can calculate the time as follows: Time = 2720 m / 343 m/s ≈ 7.94 seconds (s)

Therefore, it would take approximately 7.94 seconds for the sound of thunder to be heard at a distance of 2.72 km [[1]].

Please note that these calculations are based on the assumption that the speed of sound remains constant and there are no other factors affecting sound propagation, such as temperature, humidity, or wind conditions.
