<span>The charged balloon will stick to a neutral wall because of the Static Electricity:
</span>
The matter is formed by atoms and these atoms are composed of electrons, protons and neutrons (the electrons have a negative charge, the protons have a positive charge and the neutrons have no charge).
As the balloon is charged (It gained electrons), and the charge of the same sign repel each other, when it approaches the wall, the electrons of this wall will move away, and the positive charges (protons) will remain in the nearest area to the balloon. As the charges of different signs are attracted, the balloon will be stuck to the wall.
In science and physics net force is the mean or overall of all the forces acting on an object.
Answer:
The answer would be C. 8 N
Explanation:
These three forces are cohesive force, adhesive force and surface tension. The cohesive and adhesive forces are opposite of each other. While cohesive force is the intermolecular bonding between like molecules, the adhesive force is the intermolecular force between unlike molecules. Surface tension is perceived to be the force exerted by the liquid near the surface of the water. Together, these forces bring about an increase in liquid height when a very small tube is placed on a wide surface liquid.
