Question

The speed of sound in diamond is 12000 m/s . How long would it take a sound wave to travel 1 Km through solid diamond?A) 0.083 seconds B) 12000 seconds C) 12 secondsD) 35.3 seconds

Answer 1

Considering the equation for velocity, we have:

`v=(\Delta s)/(\Delta t)\Rightarrow\Delta t=(\Delta s)/(v)`

In our case, we'll have:

`\Delta t=(1000)/(12000)=0.083s`

Then, our answer is A) 0.083 seconds
