not all are objects so pick the ones that are.
an object has a mass of 57.6g . find the object's density, given that's it's volume is 40.25cm^3
Answer:
The answer is 1.43 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 57.6 g
volume = 40.25 cm³
We have
[tex]density = \frac{57.6}{40.25} \\ = 1.431055900...[/tex]
We have the final answer as
1.43 g/mLHope this helps you
what is the role of the sun in forming convection currents in earths water and air?use scientific reasoning to construct your answer.
Answer:
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds. I hope this helps
The sun heats the air near the equator of the earth, it becomes less dense and rises upward. As warm air rises, it cools and gets less dense than the air around it.
What is convection?Convection can be d defined as the transfer of heat from one place to another due to the movement of heat or fluid. Convective heat transfer involves the processes of conduction as well as advection.
Gases and liquids can not be good conductors of heat under normal conditions, but they can easily transfer heat.
Convection occurs through diffusion or advection but does not take place in solids, as there is no movement of its constituent particles happens. The diffusion of heat in solids is known as thermal conduction.
The heat transfer that occurs between a surface and a liquid that is in contact with the surface is convection heat transfer.
The Sun provides the energy for the convection in the ocean and produces ocean currents. There are two kinds of ocean currents: one is surface currents and the other deep currents.

What is the most likely reason that nonmetals are electrical insulators?
Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.
Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
Since all nonmetals have valence shells that are full, they hold electrons tightly to avoid changing.
Since all nonmetals have valence shells that are completely empty, they do not attract or release any electrons.
Answer:
Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.

describe a procedure to remove the water from the mixture that passes through the filter and collects in the beaker.
Answer:
The procedure is Filtration
Explanation:
Filtration is a process that is use to separate insoluble solid from liquid for example Salt and water.
This process uses filter paper which is placed inside a funnel and then placed inside a beaker.
The mixture of sand and water is poured into the the filter paper and water then drains out down to the funnel and the beaker.
The solid part remain at the filter paper and it is called the residue and the water is the filtrate.
How many grams of Sodium will have the same number of atoms as 6 grams of Magnesium?
Atomic mass of Sodium is 23 u and atomic mass of Magnesium is 24 u.
Answer:
92gm
Explanation:
Atomic mass of Mg=24g=1 mole of Mg
∴ 24g =1 mole of Mg contain 6.022×10^23 atom
∴ 6gm contains 246.022×1023×6
=4×6.022×10^23 atoms
Now according to question, there are 6.022×1023 atoms of Na
23gm of Na contains 6.022×10^23 atoms
∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm

Define physical change
Answer to Question.
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
kinetic energy is energy that an object possesses because of its
Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.
I have learned that the law of acceleration can be applied in the
following situations
1.
2.
3.
helpppp poooooo
Answer:
See explanation below
Explanation:
Let's recall what's the law of acceleration.
First of all, the acceleration is a vector that has the change of velocity in function of the time.
Now, the law of acceleration is related to Newton's Second law which states that an object will move only if there are forces around it. In other words, the following expression:
F = m . a
Now, in this case, we know that the acceleration of an object is affected by a force always. So, if an object stand still, it will not move unless you push it or pull it to move, and the acceleration will speed up or down depending of the force it was exerted.
According to this, the law of acceleration can be applied here:
1. A bike going down a hill. Of course, because, let's suppose you let a bike alone go down on a hill, you will see that the speed of the bike will be faster as time goes by. This is because the force acting here is the weight of the bike and gravity.
2. Dropping a ball from a building. In this case, you drop a ball from a high floor on a building, it will happen the same thing as the bike. It will go faster because of gravity.
3. Putting the break on a car. Now in this case it's easy because you only need to know that when you put the brakes, the speed of the car will go down, but also the acceleration. So there's no need of a further explanation of this.

Answer:
40 C atoms
Explanation:
Step 1: Write organic compound
10C₄H₁₀
We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.
We are given that we have 10 moles of C₄H₁₀.
Therefore, we have 4 · 10 = 40 atoms C

Purview is the word that best replaces reach without changing the meaning of the sentence. Therefore, the correct option is option B.
What is statement?A sentence is indeed a collection of words used to express a thought. A sentence always begins with such a capital letter then concludes with a period, punctuation mark, and exclamation point. Ideal sentence construction has a verb and a subject. Declarative sentences make a declaration, express an opinion, or make an emotion known.
Declarative sentences have a period at the end. Questions are asked in sentences known as interrogatives. These phrases are followed by a question mark. This kind of phrase is used to give instructions or make a request. There is typically a period at the end, but occasionally there is also an exclamation point. Univocal means having only one possible meaning. Purview is the word that best replaces reach without changing the meaning of the sentence.

The compound acetaldehyde most likely contains the functional group shown below:
-C-
downwards equal sign
O
true or false.
True
Further explanationAldehydes are alkane-derived compounds containing the functional group (-CO-) located at the end of the parent carbon chain
The general structure is R-CHO with the molecular formula CnH2nO
Naming is generally the same as the alkane by replacing the suffix with -al
Acetaldehyde(ethanal) is an aldehyde which has 2 C atoms with formula
[tex]\boxed{\bold{C_2H_4O}}[/tex]
The bond between the C atom and the O atom is a double bond
