Answer:
Mechanical dissection
Explanation:
Taking apart old things and innovating to improve upon them is mechanical dissection.
Solution :
Given data :
p = 315612 Pa
At exit of B,
p =
At exit of A,
We need to determine X component of force () to hold in its place.
From figure,
Substitute all the values,
Therefore, the force required to hold the nozzle in its place along horizontal direction.
Answer:
the percentage of light that gets through this combination is 9.38
Explanation:
Given the data in the question;
Let us represent the incident unpolarized light with .
So, the amount of light intensity passing through the first polarizer will be;
= / 2 ------ let this be equation 1
An the amount of light intensity passing through the second polarizer will be;
= cos²θ
given that; the second one has its transmission axis at 30°
so, we substitute;
= × cos²( 30° )
= × 0.75
= 0.75
from equation; = / 2
= 0.75( / 2 )
= 0.375 .
Now, the amount of light intensity passing through the third polarizer will be;
= cos² ( 90° - 30° )
= × cos²( 60° )
= × 0.25
we substitute
= 0.375 × 0.25
= 0.09375
∴ / × 100 = 0.09375 × 100
⇒ 9.38%
Therefore, the percentage of light that gets through this combination is 9.38
Answer:
411.953 kpa
Explanation:
We have the following assumptions
1. Steady incompressible flow.
2. Burst section water pressure = water main pressure
3. Air and water have negligible friction between them.
Max height = 42 m
Max water density = 277.14k
Density of water
Pwater = 999.8395kg/m
Water gets to 42m because of pressure in the line
P (line) = Pwater * g * h
= 999.8395 x 9.81 x 42
= 411.953Kpa
