A block of plastic released under water will come up to the surface of the water because the density of the plastic is less than the density of water.
<h3>
What is density?</h3>
Density is the amount of mass a substance contains per its unit volume. It means the number of particles that can be packed into a unit space of that substance.
<h3>
How does density determine whether an object will float or sink?</h3>
When an object is immersed in a liquid, it experiences two forces - gravitational force and an upward buoyant force called upthrust. If the density of the object is more than the density of the liquid, gravitational force will be greater than upthrust and the object will sink, but if the density of the object is less than the density of the liquid, upthrust will be greater than gravitational force and the object will float. That is why a block of plastic will come up to the surface when released under water, because it is less dense than water.

The main units for acceleration are <span>the meter per squared second as told by Galileo Galilei. Although there can be more than one example, I consider this one to be correct. Hope it will help you in some measure.</span>
Answer:
Q.5 - Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats.
Q.6 - An adaptation is a special skill which helps an animal to survive and do everything it needs to do. Adaptations could be physical changes to the animals body or behavioural changes in how an individual animal or a society do things in their daily lives. ( I may not be right )
Q.4 - Whereas weather refers to short-term changes in the atmosphere, climate describes what the weather is like over a long period of time in a specific area. Different regions can have different climates.

I think there is no need for explaining :)
Answer:
There are equal parts reactants and products.
Explanation:
When a system is in a chemical equilibrium, the rate at which the forward reaction occur is the same as the rate at which the reverse reaction occurs. This system is said to undergo a reversible reaction. The concentration of the reactants and products do not change, i.e are constant.
In a chemical equilibrium, the reaction continues in both directions but at the same rate.
Therefore the statement that is a misconception about a system in chemical equilibrium is 'There are equal parts reactants and products'.
Answer:
what language is that? but I believe the answer is the star gazing race. It's pretty fascinating how the colonial ridges fought.
