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
Let A = i+j+k be a vector and B = 3 be any scalar,
Multiplying A and B,
AB = (i+j+k)3 = 3i+3j+3k
Which is a new vector whose direction is same as the old but it's 3 times greater in length than the old vector(i+j+k).
Now, dividing A and B,
A/B = (i+j+k)/3 =

Which is again a new vector whose direction is same as the old but now it's 1/3 times small in length than the old vector.
Direction is same because we multiplied by positive scalar. If we multiply A by suppose -1, -4, -1000000 or any negative number, it's direction will reverse.
Thus, if we multiply a vector with scalar, it's length increases. If we divide, it shrinks.
Answer:
conductor:-
A substance that allows heat to pass through them is known as a conductor.
Example:-All the metals, water, etc.
Insulator:-
A substance that does not allows heat to pass through them is known as an insulator.
Example:-All the nonmetals etc.
Explanation:
Answer:
7.6*10^4J
Explanation:
Given that m=95kg
Final velocity= 40m/s
Using W=0.5 m (square of (final velocity) - square of (initial velocity))
= 0.5 * 95 * Squared of (40)
= 7.6*10^4J
The speed of a falling object<span> is not </span>affected<span> by the </span>mass<span> of the </span>object<span> ...
