Answer:
a frisbee flaying in the air
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules. M represents mass measured in kilograms. V represents velocity measured in metres per seconds square.Hence, an example of kinetic energy at work is a frisbee flaying in the air because it would possess energy due to its motion in the air.

If 2.33L of propane (C3H8) at 24.0C and 67200 Pascals is completely burned with excess oxygen, how many moles of carbon dioxide gas will be produced?
Answer:
0.182 moles of CO₂ are produced by this combustion
Explanation:
First of all, we state the combustion reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
As we do not have data from the oxygen, we assume it as the excess reactant. Let's determine the moles of propane, by the Ideal Gases Law.
We convert pressure from Pa to atm
67200 Pa . 1 atm /101300 Pa = 0.663 atm
P . V = n . R . T
0.633 atm . 2.33L = n . 0.082 . 297K
(0.633 atm . 2.33L) / (0.082 . 297K) = n
n = 0.0606 moles
Now we analyse the stoichiometry. Ratio is 1:3.
1 mol of propane can produce 3 moles of carbon dioxide
Then, 0.0606 moles of propane may produce (0.0606 . 3) /1 = 0.182 moles
In conclussion, 0.182 moles of CO₂ are produced by this combustion
What property of water is responsible for water transports in plants?
A.moderation of temperature
B.insulation
C.its versatility as a solvent
D.cohesion
E. its role as a buffer
Answer:
Cohesion
Explanation:
D. you're welcome
One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem (the vascular tissue responsible for the transport of water), from the roots all the way to the leaves.
3. Your friend's new car can go from 0 to 60 m/s in 7 sec. What is the acceleration?
Answer:
Initial velocity (u) = 0 m/s
Final velocity (v) = 60 m/s
Time (t) = 7 sec
Acceleration (a) = ?
a = (v-u)/t
a = (60-0)/7
a = 60/7
a = 8.57 m/s²
How many moles of magnesium are required to react with 2.0 mol of hydrochloric acid? The equation for this reaction is Mg + 2HCl → MgCl2 + H2.
Answer:
1 mole of magnesium are required to react with 2.0 mol of hydrochloric acid.
Explanation:
The balanced reaction is:
Mg + 2 HCl → MgCl₂ + H₂
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products. That is, the law of conservation of mass implies that the sum total of charges before and after the chemical reaction remains constant.
The relationships between the quantities of reactants consumed and products formed depend directly on this conservation law, and therefore can be determined by an equation that describes them. This equality is called the stoichiometric equation.
In this case, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), you have:
Mg: 1 moleHCl: 2 molesMgCl₂: 1 moleH₂: 1 moleThen, 1 mole of magnesium are required to react with 2.0 mol of hydrochloric acid.
Answer:
1 mole of magnesium, Mg
Explanation:
The balanced equation for the reaction is given below:
Mg + 2HCl —> MgCl₂ + H₂
From the balanced equation above,
We can see clearly that 1 mole of Mg requires 2 moles of HCl.
Thus, 1 mole of magnesium, Mg is needed for the reaction.
What causes a repeating pattern of day and night
Answer:
Rotation of the Earth causes night and day to alternate. Since we learned that the Earth's axis is tilted and hence the equator is not facing the Sun directly, different places on Earth would experience unequal length of days and nights—not exactly 12 hours of day and 12 hours of night all the time.

Whic statement compares the energy transformations that occur in the ecosystem within photosynthetic organisms?
A Solar energy is converted to thermal energy, which increases food availability for the ecosystem.
B Solar energy is converted into chemical potential energy, which is found in the products like glucose.
C Chemical erlergy in carbon dioxide is converted into solar energy, which provides a mechanism to produce food for the ecosystem.
D Kinetic energy of the reactants is converted to potentia. energy in the products, which can be metabolized within the ecosystem.
Answer:
B.
Solar energy is converted into chemical potential energy, which is found in the products like glucose.
Explanation:
According to photosynthesis phenomena ,the statement which compares energy transformations in ecosystem within photosynthetic organisms is statement B.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Ben has a snack with a combination of raisins, chocolate pieces, and nuts. As he eats the snack, Ben picks out all of the raisins.Which BESTdescribes the snack Ben is eating
Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts. It has since changed to include various different ingredients such as a variety of nuts, chocolate pieces, dried fruit, cereal etc.

How are the four kinds of DNA nucleotides different from each other?
Answer:
The sugar in DNA is deoxyribose. ... Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring.
Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.
What are nucleotides ?Nucleotides are organic compounds made up of a phosphate and a nucleoside. They function as monomeric units of the deoxyribonucleic acid and ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth.
Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.
The quantity of phosphate residues that a nucleotide has determined its name. Adenosine triphosphate, for instance, is the name of a nucleotide that consists of an adenine base and three phosphate residues (ATP). Adenosine diphosphate would be the nucleotide if it has two phosphates (ADP).
Thus, Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA.

The pressure of a piston with a volume of 650 cm3 and 85ºC is 830 mmHg. It is heated to 350ºC and compressed to a volume of 65 cm3. What is the new pressure?
Answer:
34176.5 torr
Explanation:
It is given that :
Initial pressure, [tex]$P_1 = 830$[/tex] torr
Initial volume, [tex]$V_1 = 650 \ cm^3$[/tex]
Initial temperature, [tex]$T_1 = 85^\circ C$[/tex]
Final volume, [tex]$V_2 = 65 \ cm^3$[/tex]
Final temperature, [tex]$T_2 = 350^\circ C$[/tex]
Therefore, using the combined gas laws, we can write :
[tex]$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$[/tex]
Substituting the values, we get
[tex]$\frac{830 \times 650}{85}=\frac{P_2\times 65}{350}$[/tex]
[tex]$P_2 = \frac{830 \times 650 \times 350}{85 \times 65}$[/tex]
= 34176.5 torr
So the new pressure is 34176.5 torr.
