Devin had a bucket of shredded metals the metals consist of aluminum steel and copper he tried sorting the mixture by running it through a filter but this did not sort the mixture into separate components what can devin conclude
Answer:
Devin's problem can be solved by exploiting the activity series of metals.
Explanation:
This determines what metals are more reactive and would be readily displaced in a reaction.
Seeing as they are both metals scraps of similar sizes, filtration isn't a solution. But since Copper is lower on the activity series than Aluminium, adding an acidic solution (say tetraoxosulphate VI solution) to the mixture, would have aluminium in solution and Cu as residue which can then be filtered off.

If the gravitational force between the two objects is 2.0×10 ^-7 N and the value of gravitational constant, G= 6.67×10 ^-11 n m² kg¯², what is the value of D?
F=Gm1m2/D*2
or,2.0×10^-7 = (6.67×10^-11 ×75×90)/D^2
or,2.0×10^-7 = (45022.5×10^-11)/D^2
or,D^2=22511.25×10^-4
D=1.5003m
how to determine whether a liquid is pure water or not besides boiling the liquid?
Answer:
Explanation:
Aside the boiling point of water, another colligative property that can be used to identify pure water (or not) is the freezing point. Water freezes at 0 °C, but with the presence of impurities, there is a freezing point depression of the water. Thus, if the water is not pure, the liquid could freeze at a temperature lower than 0 °C (with a negative sign like -8 °C).

Chemical reaction
It is a process where one or more substances that we know as reactants should be transformed into one or more distinct substances that we know as products. Here the substances should be treated as the elements of chemicals or the compounds.Chemical reactions are an integral part of technology, culture, and indeed of life itself. Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years. Chemical reactions abound in the geology of Earth, in the atmosphere and oceans, and in a vast array of complicated processes that occur in all living systems.Therefore, Some non-examples of the chemical reaction should be boiling water, glass breaking out, etc.

A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. What best explains the increase in the size of the panther population?
Explanation:
Because the panthers live in the southeastern region of the United states they have increased in population in that region. They have been able to gain more food and have adapted more to there environments. Which allows to increase and reproduce more. That is why the Panthers in the southeastern United states have increased In population. I hope this works for you and that it helps. I don't mind helping someone who has a question! From, me.
A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. More panthers were born than died explains the increase in the size of the panther population.
What is the largest panther in the world?The jaguar, also known as the panther, tigre, or onza, is the world's largest and most powerful cat. Human activities endanger this cat, as they do the Florida panther (Puma concolor).
Because the anteater population will have fewer energy storage molecules available due to the smaller ant population, the anteater population will reproduce less.
Panthers can be found in the southeastern United States. The region's panther population has grown over the last 50 years. Because no animal eats panthers, the panther population is always growing.
Thus, More panthers were born than died explains the increase in the size of the panther population.

Explanation:
Sunlight heating the sand on the beach on a hot summer day is an example of radiation which is electromagnetic radiation.
What is electromagnetic radiation?
The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
