Question

Suppose your friend is 510 m away along a long iron railing while you have your ear to that railing. She taps the railing with a stone. How long will the sound take to reach your ear?

Answer 1

t = 0.1 s

Step-by-step explanation:

We know that sound travels at different speeds through different materials, so we first need to find the speed of sound through iron. Consulting a table, we find that the speed of sound through iron is 5100 m/s.

Next, we need to calculate the time it takes for the sound to travel from the point where the stone was tapped to our ear, a distance of 510 m. We can use the formula:

time = distance/speed

Plugging in the values, we get:

time = 510 m / 5100 m/s

Simplifying, we get:

time = 0.1 s

So the sound will take 0.1 s to reach our ear.

Answer 2

Step-by-step explanation:

search and find the speed of sound in metals. i am going to take it as X.

S= ut

510= X*t

510/X= t

So, the answer is 510/X
