Answer:
Move slowly and reach bottom later.
Explanation:
Viscosity is termed as the thickness or consistency of any liquid or semi liquid. It is related to the internal friction of the substance.
When several liquids are poured down with equal path lengths then the liquid will high viscosity will reach the bottom latter while one with less viscosity.
The internal friction of the molecules tends to keep them together making its consistency more thick. Thus when it will slope down from a certain height it will take more time to reach down.
Answer: Option A
Explanation:

This is so because the charges are opposite and they will attract each other. Yes, the only condition should be that the charges should be alike.
Example: a negative charge and a positive charge.
