During 30.0 s, a train was moving with constant speed of 72 km/h. How far away it could relocate within this time?

the distance is 0.6 km

Explanation:

The computation of the distance is shown below:

As we know that

Distance = Speed × time

where

Speed = 72 km/h

And, the time is 30 seconds

So, the distance is

= 72 × 30

= 0.6 km

Hence, the distance is 0.6 km

the results is a decrease in air temperature with an increase of altitude.

explanation:

the body's situation won't change the forces are equal opposit and on the same body
