Answer:The idioms in over one’s head and over one’s head differ by only one, small, preposition. However, this preposition makes the definitions of these two phrases totally different. An idiom is a word, group of words or phrase that has a figurative definition that is not easily deduced from its literal meaning.
Explanation:
There is no "following sentence" so I don't think you're ever gonna get an answer...
Do you recall which sofa was the most comfortable? Indirect.
Given:
Potential difference between capacitor plates = 2.6 V
Dielectric constant of paper , K = 3.7
Solution:
When air is filled, let the potential difference between capacitor plate be V'
Now, after being disconnected from the battery, the charge stored in the capacitor will remain constant
And when dielectric is introduced between the capacitor plates, the potential difference will be reduced by k times a:
V =
Therfore, V' = KV = 3.7 × 2.6 = 9.62 V
The resulting potential difference of the capacitor, V' = 9.62 V
