Red shift in the light coming towards us from other galaxies.

**Answer:**

Q=22.6L/s

**Explanation:**

First you must consider the continuity equation at points 1 and 2, which indicates that both flows are of equal value, in this way you get an equation between the two flow rates.

Then you raise the Bernoulli equation taking into account that the height is the same, which makes the term h1-h2 zero.

Using the equations above to calculate one of the speeds.

Finally you find the flow by multiplying the speed by the area.

I attached procedure

A squared plus b squared equals c squared

**Answer:**

750 force

**Explanation:**

I have never worked with force but I can guess using the formula. 1500, which is the mass, multiplied by the acceleration, 0.5, would equal 750 force, if being applied by the equation listed, Force= mass×acceleration
