Conservation of Energy:
As a projectile is launched into the air KE is at its maximum. As the projectile gains altitude PE becomes greater than KE. At the top of its arc, PE is at its maximum. The whole cycle reverses itself on the way down.
Chemical composition and physical properties
Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is : The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test <u>color, malleability, melting points</u>, and to test how shiny or dull it is. I would propose these to increase the <em>certainty</em> in the identity of the metals. Btw, please mark me brainliest.
Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".
The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
Global warming. Not reversing it, because that would most likely cause an ice age, but keeping it under control.
Answer:
1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.
2-The existence of oil fields, or oil towers for the manufacture of fuel.
3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.
Explanation:
In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.
