pyaal dedo ♥ A girl standing infront of a wall at a distance of 90 m produces 2 claps per second she notices that sound of his clapping coincides with the echo. The echo is heard only once when clapping is stopped.Calculate:—Speed of sound About the author Hailey
Answer: 360m/s Step-by-step explanation: In the question, it is given that the distance traveled by sound is 2×90= 180m as it is a reflected or echo sound. We know that time taken is the inverse of frequency. Hence, the time taken is calculated as follows. T= 1/2=0.5seconds d=vt/2 v=180/0.5 = 360m/s Reply
Answer:
360m/s
Step-by-step explanation:
In the question, it is given that the distance traveled by sound is 2×90= 180m
as it is a reflected or echo sound. We know that time taken is the inverse of frequency.
Hence, the time taken is calculated as follows.
T= 1/2=0.5seconds
d=vt/2
v=180/0.5
= 360m/s
