On a large scale, electric forces can interact between objects over significant distances and have a noticeable impact on large objects. They follow the inverse square law, meaning the force decreases as the distance between objects increases. Additionally, electric forces can be both attractive and repulsive, leading to behaviors such as the movement of charges in electric circuits or the formation of lightning.
On a large scale, electric forces tend to cancel out due to the presence of positive and negative charges in equal amounts in most matter. This results in matter being mostly electrically neutral overall.
False. Electric forces are forces that act on charged objects due to their electric charges. Friction and other contact forces are caused by the interaction between surfaces in contact with each other, typically due to mechanical interactions at a microscopic level.
False. Electric forces are caused by the interaction of charged particles (like electrons and protons), but friction and contact forces are primarily a result of mechanical interactions between objects.
True. The weight reading on a scale measures the downward force exerted by an object due to gravity.
True. The strength of an electrical field follows an inverse square law.

No. The electric force in this case decreases.
Electric forces are responsible for holding atoms and molecules together. Atoms and molecules are the building blocks of matter, and require both attractive and repulsive forces to maintain balance. Therefore, electric forces are the foundation for the existence of all matter.

True, continents are large pieces of land that are part of tectonic plates, which are constantly moving due to forces beneath the Earth's surface.

Industrial chemistry primarily deals with manufacturing compounds on a commercial scale and economic scale for large-scale production in industries. Typically, laboratory work focuses on research and development of new compounds, while micro-scale production may involve small-scale testing or pilot projects before full-scale production.
Hydro power is expensive up front in a large scale but eventually pays for itself. This is particularly true with hydroelectric dams which power large areas.
