Velocity = distance / time

v = d /t

    =  4ms⁻¹ / 40s

v =   0.4 ms⁻²    .

If a freely falling object were equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s², then i
babymother [125]

Answer:

20 m/s

Explanation:

The acceleration of an object determines the increase in velocity per second.

In this case the acceleration is 20m/s^2.

a=\frac{v}{t}=\frac{\frac{20m}{s}}{s}

That is, the increase is 20m/s each second.

I hope this is useful for you

Explain how if a solid, liquid, and gas are put into individual containers how they fill the container.
Sav [38]

Answer:

serial in which container is filled

Solid -base of container

Liquid- above solid

Gas- above liquid

Explanation:

If any mixture of  matter in different state (that solid , liquid or gas )are kept in any container, then substance with higher density will be settled at lowest surface first and similarly the substance with lowest density will be at upper part of container.

In the given container we have to keep solid, liquid and gas

  • sold has the highest density,
  • gas the lowest density and
  • liquid has the density higher than gas but less than solid.

based on this

solid will be at surface of container

above sold will be liquid

above liquid will be presence of Gas

serial in which container is filled

Solid -base of container

Liquid- above solid

Gas- above liquid
