Answer:
For melting snow and ice, salt, liquid calcium chloride and a few other de-icing chemical products are clearly superior to sand, or a sand/salt mixture. In fact, sand by itself has no de-icing capacit
Explanation:
By the law of conservation of energy, the energy input to a system must equal the output. However, when there are more moving parts in a machine, like in a complex machine, the energy converted to non-useful energy, such as the production of heat energy via friction, is increased. Therefore, the more the moving parts, the greater the losses of energy due to increased friction. This is why complex machines are less efficient.
Answer:
Water.
Explanation:
Osmosis is the diffusion of water across a memnbrane.
Flowing water slows down when it reaches flatter land or flows into a body of still water. The water starts dropping the particles it was carrying. As the water slows, it drops the largest particles first. The smallest particles settle out last.
I don't know if this helps but hopefully it did x
