C.

D.
insufficient supply of oxygen
Answers
Answer:
D. insufficient supply of oxygen
Explanation:
Combustion is an exothermic reaction which involves the burning of a compound in the presence of oxygen. Combustion is a very useful life process as it produces heat and light.
For a complete combustion reaction to occur, the compound must be burnt over excess oxygen. The product is usually carbondioxide and water with release of some particulate matter.
In incomplete combustion, there is deficiency of oxygen. Here, oxygen becomes the limiting agent and it drives the reaction to an end. Incomplete combustion is always accompanied with the production of poisonous carbon monoxide and Carbon. We see incomplete combustion when smoke forms or when burning is accompanied by production of soot.
What makes a combustive process complete or not is the availability of oxygen gas for the reaction.

Answer:
The kinetic energy at the 0.500 position is 1.96 J.
Explanation:
Mass of the vase = 0.800 kg
Height from where vase fallen = 0.750 m
Potential energy of vase at 0.750 m:
Kinetic energy of the vase at the point just before it was about to fell:
(absence of motion)
P.E + K.E = 5.88 J + 0 J = 5.88 Joules
Potential energy of vase at 0.500 m:P.E'
Kinetic energy of the vase at the point 0.500 m above the floor: K.E'
As we know, that sum of P.E and K.E remains constant.;
P.E' + K.E' = 3.92 J + K.E' = 5.88 J
K.E' = 5.88 J - 3.92 J = 1.96 J
The kinetic energy at the 0.500 position is 1.96 J.
Answer: The kinetic energy of vase at 0.500 m position is 1.96 J
Explanation:
Law of conservation of energy states that energy can neither be created nor be destroyed but it can only be transformed from one form to another form.
Here, the potential energy of the vase is getting converted into kinetic energy of the vase
So, calculating the potential energy of vase, we use the equation:
P = mgh
where,
m = mass of vase = 0.800 kg
g = acceleration due to gravity =
h = height of vase = (0.750 - 0.500) m = 0.250 m
Putting values in above equation, we get:
At 0.500 m, the potential energy gets converted to kinetic energy.
Kinetic energy of the vase = 1.96 J
Hence, the kinetic energy of vase at 0.500 m position is 1.96 J

Drosophila eye color is an X-linked trait. Red eye color is dominant, and white eye color is recessive when two parents have the genotype of allele like XXi XY in which the Xi will be the allele for the 25% of red eye color.
Explanation:
We know that punnet square is a diagrammatic representation to predict the result of cross as well as breeding experiment. This is being used for getting the probability of offspring with particular genotype. Based on the best possible answer if the two parents have the genotype of allele like XXi XY in which the Xi will be the allele for the red eye color. The eye color gene is present in the X chromosome.

Explanation:
One food Calorie is equal to 1 kilocalorie, that is, 1000 calories. A SI unit of energy is the joule (symbol J), where 1 cal = 4.184 J. The heat produced by chemical reactions is often expressed in kilocalories, as well as in kilojoules (kJ), where 1 kcal = 4.184 kJ.
Final answer:
First, we convert the energy of the photon to Joules. Then, we use the equation for energy of a photon, E=hc/λ, rearranged to solve for λ (wavelength). Substituting the known values into this equation, we can calculate the wavelength of the photon.
Explanation:
The energy of a photon is given in calories, but in physics, it's usually measured in Joules, so we first need to convert our energy to the appropriate unit. Thus, the energy of the photon is 4184 Joules (1,000 calories x 4.184 Joules/calorie).
The energy of a photon is also related to its wavelength through the equation E=hc/λ, where h is Planck's constant (6.63 x 10^-34 J.s) and c is the speed of light (3.00 x 10^8 m/s). By rearranging the equation, we find λ=hc/E. Substituting the given numbers for Planck's constant, the speed of light, and the energy of the photon, we find that λ = (6.63 x 10^-34 J.s)(3.00 x 10^8 m/s) / 4184 J.
Calculating these values, we will arrive at the wavelength of the radiation emitted by this photon.

No because they have their complete octet. They are completely filled and don't need to bond with any other atoms. The full atoms that are happy are the noble gases.
What are noble gases ?
Noble gases have electron shells with full valence. Valence electrons are the atom's outermost electrons and are typically the only electrons involved in chemical bonding.
Noble gases are elements that have completely filled their valence shells, completing their octets. Helium, Neon, Argon, Krypton, Xenon, and Radon are examples of noble gases.
Thus, the elements like He, and Xenon can not form bond with other atoms because they have completely filled orbital so, they are not loosing or gaining any electron from other atoms, that's why they are called “happy, full” elements.
