Answer:
Explanation:
The Bernoulli equation tells us that in a fluid , so we will apply this to <em>a point on the surface and a point on the hole</em>.
For a point on the surface (at height ) the velocity will be approximated to 0m/s since <em>we assume it barely moves</em> (unless other information is given), so we have:
For a point on the hole (at height and velocity of the fluid ) we have:
Since both constant are the same, cancelling we have:
Which means:
So the velocity of the fluid flowing through the hole will be:

Explanation:
<u>Densidad</u>
La densidad de una masa m que ocupa un volumen v se define como:
Tenemos que una masa de 80 gr hace que un volumen de agua se desplace desde 60 cm3 hasta 75 cm3, es decir, el volumen propio de la masa es m = 75 - 60 = 15 cm3.
Con esta información se calcula la densidad:

Complete question:
A uniform electric field is created by two parallel plates separated by a
distance of 0.04 m. What is the magnitude of the electric field established
between the plates if the potential of the first plate is +40V and the second
one is -40V?
Answer:
The magnitude of the electric field established between the plates is 2,000 V/m
Explanation:
Given;
distance between two parallel plates, d = 0.04 m
potential between first and second plate, = +40V and -40V respectively
The magnitude of the electric field established between the plates is calculated as;
E = ΔV / d
where;
ΔV is change in potential between two parallel plates;
d is the distance between the plates
ΔV = V₁ -V₂
ΔV = 40 - (-40)
ΔV = 40 + 40
ΔV = 80 V
E = ΔV / d
E = 80 / 0.04
E = 2,000 V/m
Therefore, the magnitude of the electric field established between the plates is 2,000 V/m

Option 2
Explanation:
The theory supported by the statement : "<u><em>Mountain ranges often appear on the edges of continents.</em></u>", is that :
- <u>Mountain ranges were formed when continents collided.</u>
