Answer:
E = 7333.33 mm
Explanation:
The annual evapotranspiration (E) amount can be calculated using the water budget equation:
(1)
<u>Where</u>:
<em>P: is the precipitation = 2500 mm, </em>
<em>Q(in): is the water flow into the river of the farmland = 5 m³/s, </em>
<em>ΔS: is the change in water storage = 2.5x10⁶ m³, </em>
<em>Q(out): is the water flow out of the river of the farmland = 4 m³/s.</em>
<em>Δt: is the time interval = 1 year = 3.15x10⁷ s </em>
<em>A: is the surface area of the farmland = 6.0x10⁶ m² </em>
Solving equation (1) for ET we have:


Therefore, the annual evapotranspiration amount is 7333.33 mm.

The Alternator is the only one from this list that I know is a car part so I chose that one
Answer:
<u><em>To answer this question we assumed that the area units and the thickness units are given in inches.</em></u>
The number of atoms of lead required is 1.73x10²³.
Explanation:
To find the number of atoms of lead we need to find first the volume of the plate:

<u>Where</u>:
A: is the surface area = 160
t: is the thickness = 0.002
<u><em>Assuming that the units given above are in inches we proceed to calculate the volume: </em></u>
Now, using the density we can find the mass:

Finally, with the Avogadros number (
) and with the atomic mass (A) we can find the number of atoms (N):
Hence, the number of atoms of lead required is 1.73x10²³.
