To answer this question is necessary to apply the concepts related to Bernoulli's equation. The Bernoulli-related concept describes the behavior of a liquid moving along a streamline. Pressure can be defined as the proportional ratio between height, density and gravity:
Where,
h = Height
= Density
g = Gravity
Our values are
density of water at normal conditions
h = 7.3m
PART A) Replacing these values to find the total pressure difference we have to
In this way the pressure change would be subject to
PART B) Considering the pressure gauge of the group as the ideal so that at a height H the water cannot flow even if it is open we have to,
Therefore the high which could a faucet be before no water would flow from it is 21.42m
Answer:
The magnitude is:
The direction of E is in the negative x-direction.
Explanation:
The electric field equation is:
Where:
- Q is the charge (we can choose the electron or the proton)
- r is the distance (in our case is at the midpoint 973/2 nm)
- k is the Coulomb constant (
)
Using the electron charge ()
The magnitude is:
The direction of E is in the negative x-direction.
