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:
C. 14.55
Explanation:
12 x 10 = 120
120 divded by 10 is 12
so now we do the left side
7 x 3 = 21 divded by 10 is 2
so now we have 14
and the remaning area is 0.55
so 14.55
Answer:
a) the cooler
Explanation:
When a tenant leaves a commercial property that he/she leased he can remove his personal items and some trade fixtures. For an item to be a trade fixture it should be:
1- a necessary product for doing business
2- removed without doing any damage to the property
3- removed from the property in a certain period of time.
The cooler only follows these conditions as compared to the other options.
