Answer:
Convex lens is used in astrology
By the use of Ohm's law, the resistance of the bulb is 121 ohms
<h3>What is electrical power?</h3>
Let us recall that power is the rate of doing work. Now we know that the voltage of the power source is 110-V and the power is 100-W.
Since;
P= IV
I = P/V
I = 100/110
I = 0.91 A
Again;
V= IR
R = V/I
R = 110/0.91
R = 121 ohms

Answer:
B) weather conditions that cannot be foreseen, and pilot errors often cause much larger deposits of spray than
Explanation:
Option B obeys the principle of parallelism because the two phrases, " can be carefully planned" and "cannot be foreseen" follow the same grammatical structure. Option A does not obey parallelism because " can be carefully planned" and "could not be foreseen" do not follow the same grammatical structure.
The phrase " they had anticipated" in the other options apart from B do not have a matching subject. Pilot errors is the subject in this sentence and it is not expected to anticipate anything, only the pilots can.
Moreover, "that cannot be foreseen" is more parallel to "can be carefully planned" that "unforeseeable" or "foreseeable" used in the other options
