7. Assume you are dealing with a vertical walled reservoir having a surface area of 650,000 mwith an inflow of 0.5 m/s. How many
finlep [7]

Answer:

So reservoir will take 455000 sec to raise 35 cm

Explanation:

We have given surface area of the reservoir = 650000 m^2

Rate of flow = 0.5 m/sec

Height through which reservoir is raise = 35 cm = 0.35 m

So volume \Delta V=surface\ area\times height=650000\times 0.35=227500m^3

We have to calculate the time

Time is given by t=\frac{\Delta V}{rate\ pf\ flow}=\frac{227500}{0.5}=455000sec

What is your opinion of the creation of artificial borders and nation states?
zimovet [89]

Answer:

I am totally against it as this type of divisions are creating differences and animosity among people, and are sometimes even leading to conflicts. I especially disagree with it from today's perspective, as people today are moving and migrating more and more and therefore the existence of nation states is nonsense.

Explanation:

I think that we should strive to the creation of political arrangements as we have in European Union.

A larger market without boundaries, with certain individualities should be something that is acceptable to all of us.

We should not create differences, but try to overcome them.
