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.

Substitute 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.

Answer:

Density is 2.7 g/ml³

Explanation:

[tex]density = \frac{mass}{volume} \\ [/tex]

mass » 13.5 g

volume » 5 ml³

[tex]density = \frac{13.5}{5} \\ \\ = 2.7 \: {g \: ml}^{ - 3} [/tex]

Answer:

[tex]\boxed {\boxed {\sf 2.7 \ g/mL}}[/tex]

Explanation:

Density is a substance's mass per unit volume. The formula for calculating density is as follows.

[tex]\rho= \frac{m}{v}[/tex]

The mass of the rock is 13.5 grams and the volume of the rock is 5 milliliters.

Substitute these values into the formula.

[tex]\rho= \frac{13.5 \ g}{5 \ mL}[/tex]

Divide.

[tex]\rho= 2.7 \ g/mL[/tex]

The density of the rock is 2.7 grams per milliliter.

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.

Explanation:

A prepositional phrase should include after the preposition an object and its modifiers. The correct option is D.

A prepositional phrase is a group of words that contain a preposition with its object and the words that modify it. These are the words that change verbs and nouns.

For example, Mansi is going out with handsome Brian. Brian is the object and the beautiful is the prepositional phrase. The three types of prepositional phrases are:

If there are two prepositional phrases used in one sentence. The other prepositional phrase will be used as an adverb.

Thus, the correct option is D. an object and its modifiers.

Answer:

In PCl5, in addition to equitorial bonds which lie in the same plane ,there are axial bonds. Since it suffers more repulsion it is longer than the other bonds. Also these are weak bondsand therefore these bonds can break easily . Because of these reasons,PCl5 is very reactive.

How to Convert a Number to Standard Form

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. ...

Count how many places you moved the decimal point. ...

Write your scientific notation number as a x 10b and read it as "a times 10 to the power of b."

Explanation:

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.

Answer:

m=104000

Explanation:

by 1km=1000m

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.

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.

ATOMIC number of element A is 3

Explanation:

Atomic number is the same as number of protons of an element.

according to the periodic table, Lithium is the element with 3 protons in its neutral state and it's atomic number is 3.

Answer:

1s22s22p63s23p64s23d9

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
