Explain the relationship between overpopulation and diminishing water supplies.
Answer:
if a place is overpopulated, they will use more water than they have.
Explanation:
pretty much the explanation right there
Answer:
Explanation:
As human populations grow they consume more water, not just by drinking, but through all of the other human activities that require freshwater such as agriculture, bathing, cleaning, etc. Overpopulation, therefore, can lead to overconsumption as populations use more water than an area can support and replenish sustainably.
Which statements describe the motion of the object represented by the graph? Select three options.
The object is moving away from the origin.
The object is moving towards the origin.
The object started at the origin.
The object started at 2 meters.
The object is traveling at a constant velocity.
Answer:
The object is moving away from the origin
The object started at 2 meters
The object is traveling at a constant velocity
Explanation:
Statements which best describe motion of object represented by graph are statement A,D and E.
What is motion?Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.
Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.
Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic mechanics is based on modern kinematics.

What volume of 9.0 M copper (II) sulfate stock solution is needed to prepare 3.0 L of a 5.0 M solution?
Answer:
The volume of 9.0 M copper (II) sulfate stock solution needed to prepare 3.0 L of a 5.0 M solution is 1.667 L
Explanation:
Dilution is a process by which the concentration of a solute in solution is reduced by adding more solvent.
In other words, dilution is the procedure followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.
In a dilution the amount of solute does not vary. What varies in a dilution is the volume of the solvent: as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
The equation used in this case is:
Ci * Vi = Cf * Vf
where
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volumeIn this case:
Ci: 9 M Vi: ? Cf: 5 M Vf: 3 LReplacing:
9 M*Vi= 5 M* 3 L
Solving:
[tex]Vi=\frac{5 M*3 L}{9 M}[/tex]
Vi= 1.667 L
The volume of 9.0 M copper (II) sulfate stock solution needed to prepare 3.0 L of a 5.0 M solution is 1.667 L

Compare and contrast the Ionization energies of groups 1&2 (Alkali and Alkaline metals) with the Ionization energies of groups 16&17 (Oxygen family and Halogens)
Answer:
Ionization energy is the energy required to remove an electron from a specific atom. It is measured in kJ/mol, which is an energy unit, much like calories. The ionization energies associated with some elements are described in the Table 1. For any given atom, the outermost valence electrons will have lower ionization energies than the inner-shell kernel electrons. As more electrons are added to a nucleus, the outer electrons become shielded from the nucleus by the inner shell electrons. This is called electron shielding .
Explanation:
a little summary
Ionization energy refers to the amount of energy needed to remove an electron from an atom.
Ionization energy decreases as we go down a group.
Ionization energy increases from left to right across the periodic table.

Vacuum-packaging food is an effective means for stopping the growth of bacteria.
true or false
Answer:
True
Explanation:
Vacuum packing is a method of packaging that removes air from the package before sealing. ... On a more short-term basis, vacuum packing can also be used to store fresh foods, such as vegetables, meats, and liquids, because it inhibits bacterial growth. Vacuum packing greatly reduces the bulk of non-food items.

What is a chromosome
Answer:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation.

Explanation:
how hot is a supergiant star compared to our sun also the size
Answer:
Stars several times more massive then the sun have a simpler, quicker, and more spectacular evolutionary sequence. Because super giants are so massive, the core temperature gets much hotter than in giants, so supergiants can fuse elements heavier than hydrogen and helium.
Answer:
supergiant stars can have masses from 10 to 70 times greater than our sun, and when it comes to Brightness, some of them can be 30,000 times brighter than our sun. the temperature range of supergiant stars spans from around 3,450k to 20,000k.

Describe two patterns in the periodic table?
Answer:
Patter 1: Ionization Energy Decreases going down a group
Pattern 2: Ions tend to gain/lose the least amount of electrons
Take oxygen, for example. Oxygen has 8 electrons. To become like a noble gas it could either gain two to become like neon or it could lose six to become like helium. So what will oxygen do—gain two or lose six? As a general rule, atoms will gain or lose the fewest number of electrons possible.

Jeremy watched a high speed car chase in Germany, and overheard that the car travelled 85.0 km in 20.5 minutes, what was the average mph of that car??
Answer:
The correct answer is - 154.2 miles per hour.
Explanation:
The velocity of an object can be calculated by dividing the distance covered by the object in a unit of time. In the given question we know that car covers 85 kilometers of distance in 20.5 minutes.
We know: 1 km = 0.621371 miles
then, 85 km = 0.621371 × 85
= 52.81 miles
Then velocity will be:
= 52.81/20.5
= 2.57 miles/minute
converting miles/minute to miles/hour
= 2.57 × 60
= 154.2
