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
The law of conservation of energy states that energy can neither be created nor destroyed; however, if you stretch out a ball in your hand and let it freely drop, the ball will not quite bounce back up to the height you dropped it from. Which of the following best explains why this happens? *
The pull of gravity negates the law of conservation of energy.
Some of the energy has to be used up to push the ball back into the air, destroying it forever.
The ball falls too quickly, so the energy does not have enough time to fully recharge.
Some of the energy is released into the air as heat (thermal energy) due to friction.

The modern atomic theory has been updated over the years as new observations of the atom have been made. What do these changes say about the strength of the modern atomic theory
Answer:
The answer is "It updates reinforce the idea, because it has been checked and modified several times, making it longer lasting".
Explanation:
The description of its empirical data throughout the world is a scientific principle. It's also based on facts and is often extensively tested by researchers. Repetitive done by scientists testing helps to enhance its body of knowledge. As just a result of advances in technology, after observation, data collection, and findings evaluation, scientific facts are checked, modified, and verified.
A student determines the volume of a rock is 12.3mL, but the rock is
actually 12.5mL. What is the percent error? Select the BEST answer.
Answer:
1.6%
Explanation:
12.5 ml - 100%
12.3 ml - x %
x = (12.3*100)/12.5
x = 98.4%
Error = 100 - 98.4 = 1.6%

calculate the mass of 3.011×10^24 molecules of water...................... plzz i need it asap plzz help me plzz
Answer:
90.10 g
Explanation:
Step 1: Given data
Number of molecules of water: 3.011 × 10²⁴ molecules
Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water
We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.
3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol
Step 3: Calculate the mass corresponding to 5.000 moles of water
The molar mass of water is 18.02 g/mol.
5.000 mol × 18.02 g/mol = 90.10 g

When moving down a Column in the periodic table what stays the same ?
Answer:
Explanation:
When we go down in a column , we are going down in a period . In going down , one additional orbit go on adding to the atom . But the total number of electrons in the outermost orbit which is also called valence electron remains the same .
For example , when we go down in the first group A , the outermost orbit go on changing like 1 s¹ , 2 s¹ , 3 s¹ . 4 s ¹ etc which represents hydrogen , lithium . sodium , potassium etc.
So we see that , it is number of valance electrons that remains constant.

physical change because even though the change caused the temperature of the water to increase,
the water's physical properties remained exactly the same
physical change because even though gas formation was observed, the water was undergoing a
state change, which means that its original properties are preserved
chemical change because gas formation was observed, which indicated that the water was
transformed into a different substance
0 chemical change because a temperature change was observed, which indicated that the water was
transformed into a different substance

Answer :
Multicellular organismsExplanation :
Coyotes are multicellular organisms.
Trees are multicellular organisms. They are made up of eukaryotic cells, which are complex cells full of organelles.
Coyotes and oak trees are not unicellular organisms but are multicellular organisms.
Unicellular organisms are living organisms that consist of only one cell. These organisms are complete and functional in their single-cell structure, carrying out all essential life processes, such as respiration, nutrition, reproduction, and growth, within that one cell. Examples of unicellular organisms include bacteria, archaea, protozoa, certain algae, and some fungi.
Coyotes and oak trees are multicellular organisms made up of many cells. Coyotes are mammals, and oak trees are plants, both of which are complex organisms with specialized tissues and organs. In contrast, unicellular organisms, such as bacteria and protists, carry out all life processes within a single cell.
