Answer:
Adhesive forces and cohesive forces
Explanation:
Cohesive forces is how much the water molecules stick to each other and adhesive forces are to which extinct they stick to other surfaces.
When we pull the paperclip upward the water molecules adhere to it due to adhesive forces. While the water on the clip is remain connected to water in the glass because of cohesive forces.
So if the adhesive forces dominates the water will be pulled out and if the cohesive forces dominate it will remain with other water in the cup.
A buffer system usually will need a weak acid, like H2CO3, which is carbonic acid, and a strong base, and the only compound that could figure a fairly strong base among the options given is Na2CO3. NH3 and NaHCO3 are weak bases and HF is a strong acid. Therefore the best answer will be letter A
The answer is Doppler Radar. Hope this helps!
