Answer:

1.4m/s

Explanation:

Average velocity is the total distance covered divided by the total time taken.

 Average velocity  = \frac{total distance }{time }  

 Total time taken  = 5s + 6s  = 11s

The first distance covered  = velocity x time  = 1.4 x 5 = 7m

     second distance covered  = velocity x time  = 1.4 x 6  = 8.4m

So;

  Average velocity  = \frac{7 + 8.4}{11}    = 1.4m/s

Rom4ik [11]

Answer:

A. gas only

Explanation:

In a gas, the molecules are in continuous, random, straight-line motion.

The molecules are independent of one another i.e The forces of attraction (cohesive forces) and repulsion between the molecules are small and negligible,As such they possess greater kinetic energy which allows them to break the force of attraction between them

In liquid, the molecules have a less random pattern of motion and they can only slide past one another.

In solid, the motion are restricted to a small place as the molecules are not free to move about but merely vibrate about their lattice points.
