Answer:
I believe the answer is B. Just took this test :) hope I helped!!
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
Answer:
Use a moistened, clean washcloth or cotton ball to wipe each eye, starting at the bridge of the nose then wiping out to the corner of the eye. Wash the rest of the baby's face with a soft, moist washcloth without soap. Clean the outside folds of the ears with a soft washcloth.
