Question

1.
A person lives at a distance of 1.32 km from
a factory. If the speed of sound in air be
330 m s-1, how much time will the sound of
factory siren takes to reach the worker?​

Answer 1

Answer:

4 seconds

Explanation:

Displacement = 1.32 km = 1320 m

Velocity of the sound = 330 m s^-1

We have velocity = displacement/time

= 1320 m/330 m s^-1

= 4 s

A person lives at a distance of 1.32 km from a factory. If the speed of sound in air be 330 m s-1, how much time will the sound of factory siren takes to reach the worker?

$\huge\mathbf\pink{Required \: Answer}$

Explanation:

$time \: = \: distance\: / \: speed \: .$

1.32km = 1320 m/s

(1km = 1000m then 1.32km = 1320m)

Speed of sounf in air = 330 m/s

time = 1320 / 330

$\large\underline\green{\sf Time \: = \: 4 \: sec .}$

Thus it would take 4 second for the sound of the factory siren to reach the worker.
