You rub a clear plastic pen with wool, and observe that a strip of invisible tape is attacted to the pen. assuming that the pen has a negative charge, which of the following could be true? select all that apply. :

a. the tape might be negatively charged.

b. the tape might be positively charged.

c. the tape might be uncharged.

d. there is not enough information to conclude anything.

option B

Explanation:

When you rub a clear plastic pen with the wool the plastic pen gets charges this phenomenon is known as frictional charging.

Due to rubbing, the pen gets negatively charged.

We know, opposite charge attract each other and the same charge repel each other.

So, when the pen is negatively charged the tape might be positively charged or the tape might be uncharged.

Hence, the correct answer is option B

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
