Explanation:
A is certainly not an opinion. It is either true, or it is not. I think it is intended as a fact.
B is an opinion (which I think is true)
C is kind of iffy. It might be true and it might be an opinion. In looking it up, it is factually incorrect. Cats are related to wildcats in the middle east.
D is also iffy. They can just eat disease free rodents. I'd classify it as more opinion than fact.
E. definitely an opinion.

104km=?
Now
104km=104×1000m
=104000m
Therefore,m=104000 ans
104 kilometers is equal to 104,000 meters.
A conversion factor is a ratio that shows how two different units of measurement relate to each other. You can convert a value from one unit to another by multiplying or dividing the original value by a conversion factor.
For example,
Since there are 1000 meters in a kilometer, we need to multiply the distance in kilometers by 1000 to convert it into meters.
So, to convert 104 kilometers to meters:
104 Km * 1000 = 104,000 meters
Therefore, 104 kilometers is equal to 104,000 meters.

Which type of bond and how many bonds would occur as carbon dioxide (CO2) is formed from carbon in Group IVA and oxygen in Group VIA?
three metallic bonds
two ionic bonds
four covalent bonds
one covalent bond
Answers
Four covalent bonds are formed as carbon dioxide (CO2) is formed from carbon in Group IVA and oxygen in Group VIA.
The periodic table is composed of eighteen groups and eight periods. The common thread that holds all the elements in a group is that they all have the same number of valence electrons in their atoms. The elements in the same period all have the same highest energy level.
Oxygen in group Group VIA has six valence electrons while carbon in group Group IVA has four valence electrons. Hence, the chemical bond in carbon dioxide CO2 must contain four covalent bonds as shown in the image attached to this answer.

A dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.
A chemical reaction is the process by which substances called reactants are transformed to another substance known as products through the breaking up or building up of bonds between the reactants.
There are different types of chemicals reaction which includes condensation reaction.
Condensation reaction involves the combination of two smaller molecules known as monomers to for one larger molecule known as polymer with the loss of water molecule.
Condensation reaction is specifically called dehydration reaction due to the loss of water molecule that is involved.
Therefore, a dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.

What net force is required to acceleterate car at a rate of 2 m/s² if the car has a mass of 3,000 kg
Answers
Answer:
6000N
Explanation:
Force = Mass x Acceleration
= 3000 x 2
= 6000 kg m/s^2 or 6000N
Answer:
[tex]\boxed {\boxed {\sf 6000 \ Newtons}}[/tex]
Explanation:
We are asked to calculate a net force. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= m \times a[/tex]
The mass of the car is 3,000 kilograms and the acceleration is 2 meters per second squared.
m= 3000 kg a= 2 m/s²Substitute the values into the formula.
[tex]F= 3000 \ kg * 2 \ m/s^2[/tex]
Multiply.
[tex]F= 6000 \ kg * m/s^2[/tex]
Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 6000 kilogram meters per second squared is equal to 6000 Newtons.
[tex]F= 6000 \ N[/tex]
The net force required to accelerate a 3,000 kilogram car at 2 meters per second squared is 6000 Newtons.

Removing the pulp (solid) from the orange juice using a juice strainer.
a chemical change
b Physical change
Answers
Taking into account the definition of physical change and chemical change, the correct option is option b. removing the pulp (solid) from the orange juice using a juice strainer is a physical change.
Two types of changes can be distinguished: physical changes and chemical changes.
A physical change is a change that makes something different without changing the composition of the material.
In other word, a physical change is a transformation in which the nature (composition) of matter does not change, so that the substances involved are the same before and after the change.
On the other hand, chemical changes are considered to be those in which the substances involved are transformed into totally different ones.
In other words, chemical changes refer to the process that involves one or more substances that become new substances with different nature and properties.
In this case, removing the pulp (solid) from the orange juice using a juice strainer is a physical change because the pulp and the orange juice are the same before and after the change and their properties do not change.
In summary, the correct option is option b. a physical change.

Tell electronic configuration of Copper?
Copper is atomic # 29 so it has 29 protons.
The neutralatom must have 29 negative charges to balance the 29
positive charges, so it has 29 electrons.
Our electron configuration must account for all 29 electrons
Look at a Periodic Table
cture from
find copper #29
let us "AUF-BAU" ( buld up) the copper electronic configuration from the Periodic Table.copper #29 is in th 4th row.
To "build up", start at row 1. this is the 1st energy level. there are noly 2 elements H and He, so it is only an "s" robital. with 2 e's. so
1s2ve 2 e's in an s orbital and 6 in p orbitals,
at row 2 (energy level 2) we have 2 e's in an s orbital and 6 in p orbitals, so
building on top of row 1, we have
1s22s22p6
at row 3 we repeat and so have
1s22s22p63s23p6
at row 4 we start with 2 e in an s orbital at the 4th energy level, so we
have
1s22s22p63s23p64s2
we now enter the d orbtals, and copper has 9 electrons in the d orbitals.
but these d orbitals are only slightly at energy level 4. because of their more complex shape, most of the orbital is in the 3rd energy level, so
we buld up for copper, #29
1s22s22p63s23p64s23d9
count the electrons and add them:
2 + 2 +6 +2 +6 +2 +9 = 29 copper's number
