Answer:
Explanation:
Given
Initial Intensity of light is S
when an un-polarized light is Passed through a Polarizer then its intensity reduced to half.
When it is passed through a second Polarizer with its transmission axis
here
When it is passed through third Polarizer with its axis to first but to second thus
When middle sheet is absent then Final Intensity will be zero
Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required =
time required =
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
Answer:
D.
a heat force generated by the flames
Explanation:
Im not sure if that is right. the answer also maybe C.
Ceq in series is calculated by 1/C1 + 1/C2 + ....
While, in parallel, Ceq= C1 + C2 + ...
So the ratio is 1/Ceq = Ceq
