If an object has a mass of 45g and a volume of 9 cubic centimeters, what is its density? been wroking forever
A.405g/cubic centimeters
B . 5g/ cubic centimeters
C > 4g/ cubic centimeters
0.2g/ cubic centtimeters
Answer:
The answer is option BExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass of object = 45 g
volume = 9 cm³
Substitute the values into the above formula and solve
We have
[tex]density = \frac{45}{9} \\ [/tex]
We have the final answer as
5.0 g/cm³Hope this helps you
Answer:
the answer is B 5g/ cubic centimeters
Explanation:
to find the density you divide the mass by the volume
How do the number of protons in an atom affect the atom's
identity?
Answer:
The number of protons in an atom define each individual element because the number of protons is the atomic number which is the defining property of an atom and never changes. The number of protons determines an atom's identity. For example, Oxygen has an atomic number of 8, so it has 8 protons, so no matter what ionic compound or molecule it's part of, every single Oxygen atom will always have 8 protons each.

describe the motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle
Answer:
They don't move
Explanation:
it may look like they move but you are moving and you are passing the objects so they are not moving other wise things like some trains or animals they move with you. I hope this helps! :D
The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving. It seems that way because the car you are in is moving, but the surrounding things aren't moving unless they are people, animals, or other cars.
What is motion ?An object changing its position with regard to time is referred to as motion. In mathematics, displacement, distance, velocity, acceleration, and speed are used to explain motion.
Motion is the shift in an object's location with regard to time. Motion includes things like a book tumbling off a table, water running from the faucet, rattling windows, etc. Even the air we breathe has motion to it! The entire universe is in motion.
Because the two observers are using distinct frames of reference, the observations differ. Different frames of reference move in relation to one another. A frame of reference is a collection of coordinates that may be used to calculate the locations and velocities of objects within it.
Thus, The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving.

Answer:
iron+flourine.............iron flouride
Fe+F2.............FeF3
the above reaction is not balanced
now to balance this reaction
2Fe+3F2...........2FeF3
now this reaction is balanced
The balanced equation is: 2Fe + 3F2 ⇒ 2FeF3
How to balance an equation?A chemical equation needs to be balanced if you want to make the wide variety of the atoms of the reactants equal to the variety of the atoms of the goods.
Given,
Iron + fluorine ⇒ Iron Flouride
Fe + F2 ⇒ FeF3
Now to balance this reaction:

Which of the examples represent potential energy A candy bar Wind A stretched rubber band Rowing a boat A ball rollinv down a hill A roller coaster at the top of a hill
Answer:
A candy bar
A stretched rubber band
A roller coaster at the top of a hill
Explanation:
Potential energy is the energy present as a result of the position of an object. This energy depicts zero motion or movement unlike kinetic energy.
A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
The other option choices depicts a type of movement .This is why the three option choices are correct in this scenario.
The examples that represent potential energy are:
A. A candy bar
B. A stretched rubber band
D. A roller coaster at the top of a hill
What is Potential energy?It is the stored energy in any object or system by virtue of its position or arrangement of parts. This energy depicts zero motion or movement unlike kinetic energy. For example : A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.

are incompressible?
A. The molecules of a gas are much smaller
than those of a solid.
B. The molecules of a solid are not attracted to
one another.
C. The molecules of a gas are much further
apart than those of a solid.
D. The molecules of a solid are much larger
than those of a gas.
C) The molecules of a gas are much further
apart than those of a solid.
A gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.
What are gases?Gases is one of the four fundamental state of matter.
Gases can be defined as phase of matter that neither have fixed shape nor have fixed volume.
The molecules of gases are far apart from each other as compare to other phases of matter.
The change in properties of volume is known as compressibility and those fluid whose volume changes are known as compressible fluids or gases.
The fluids which does not compressed or expanded and its volume remain constant are known as incompressible fluids or gases.
Thus, gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.

Describe how you would measure the density of a boat (how would you predict if it would float )
Answer:
Please find the description below
Explanation:
The density of a substance refers to its mass per unit of its volume i.e the amount of a substance contained in a given volume. The density is calculated using the formula:
Density = mass/volume
Using this formula, with the known value for mass and volume of the boat, the density of the boat can be calculated.
An object will FLOAT on a liquid substance if its density is lower than that of the liquid while it will SINK if it has a higher density than that of the liquid.
In this case, with a known density of water, which is 1g/cm^3 or 1000kg/m^3,
a boat placed on water will FLOAT if its density is <1g/cm^3 (less than) while it will SINK if its density is >1g/cm^3 (greater than).

What is the difference between the dependent variable and the independent variable in an experiment?
An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable
Explanation:Variables are the factors or the numbers used as a quantity. The dependent variables are conditional, and the independent variable is the cause that affects the result.
What are dependent variables and independent variables?The independent variable of an experiment is the data that is the cause of the experimental design. Its value and result do not depend on other factors and conditions. These values are manipulative and are set by the researcher.
The dependent variables, on the other hand, vary based on the other factors and variables and are the effect that is based on the response and the outcome of the other variables. It is the tested or the measured value.
Therefore, the independent and dependent variables differ based on cause and effect.
