Question

You see condensed steam expelled from a ship's whistle 4.47 s before you hear the sound. If the air temperature is 20.1°C,how many meters are you from the ship?

Answer 1

Answer:

you are 1535.35 meter from the ship

Explanation:

given data

time =  4.47 s

temperature = 20.1°C

to find out

how many meters are you from the ship

solution

we know that distance formula

distance = speed × time    ........................1

and

here we know the formula of speed of sound at any temperature is

Speed of sound = (331.3 + 0.606 × T)   m/s

here T is temperature

so speed will be

Speed = 331.3 + 0.606 × 20.1

speed = 343.48 m/s

so from equation 1

distance = 343.48  × 4.47

distance = 1535.35

so you are 1535.35 meter from the ship
