The time, in seconds, that it takes a pendulum to swing back and forth is modeled by the equation below. f (l) = 2 pi StartRoot StartFraction l Over 32 EndFraction EndRoot, where l is the length of the pendulum in feet What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?

46.08 feet.

Step-by-step explanation:

Given that, for length, feet, the time period, , of the pendulum is

.

As the time period equals the time taken by the pendulum in one back and forth motion, so, actually, the given seconds to swing back and forth is the time period.

Let feet be the length of the pendulum for the time period seconds, so

[squaring on both the sides]

Hence, the approximate length of a pendulum that takes seconds to swing back and forth is 46.08 feet.

i think it might be a but you might want a second opinion

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
