Question

The smoke from the gun barrel is seen 2 second before the explosion is heard if the speed of sound in air is 340m/s calculate the distance of observer from gun

Answer 1

it is 680 m ...Distance = speed × time

Answer 2

Answer:

The distance of observed from gun is 680m

Explanation:

Distance = Speed x Time

Distance = 340 x 2

Therefore, Distance = 680

By adding the unit of distance,

Distance = 680 m

Distance:

• The total length of path through which a body moves, is called the distance travelled by it.
• The distance travelled by a body depends on the path followed by the body.
• It is a scalar quantity.
• It is generally represented by the letter S .
• The SI unit of distance is metre and CGS unit is centimetre
