How far away is a train if you see the steam from it’s nozzle 5sec before you hear it’s sound(take the speed of sound is 331m/s)

so the train is 1655m away

Explanation:

speed of sound=331m/s

time taken=5s

distance=?

as we know that

speed=distance/time

here we have to find the distance

speed×time=distance

distance=331m/s×5s

distance=1655m

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
