Answer:

The speed will be 42 m/s

Explanation:

Wavelength is the minimum distance between two points on the wave that are in the same state of vibration. In other words, in a periodic wave the wavelength is the physical distance between two points from which the wave repeats.

Frequency (f) is the measure of the number of cycles or repetitions of the wave per unit of time. That is, it is the number of vibrations that occur in a unit of time. That is, how many peaks or valleys are repeated in a unit of time. If the unit of time is one second then the frequency is measured in Hertz (Hz).

The wavelength (λ) and the frequency (f) are two inversely proportional parameters and related by the propagation speed. The speed of propagation is the speed with which the wave travels, it is represented by the letter "v". The equation that links these three parameters is v = f * λ.

In this case:

Replacing:

v= 14 Hz* 3 m

Solving:

v= 42 m/s

The speed will be 42 m/s

Answer:

This question is incomplete, but it can be answered based on general knowledge of the topic. The answer is RED

Explanation:

This question is describing a gene that codes for color. The allele for red color is R while that of white is r, however, these two alleles exhibit incomplete dominance to form an intermediate phenotype that is PINK (Rr).

Since the heterozygous is pink color, it will take two red alleles to make a plant phenotypically red i.e RR. Note that, genotype "rr" will be white.

The two most abundant compounds in air are the gases carbon dioxide, CO2, and water vapor, H2O

Answer:

Nitrogen

Explanation:

Nitrogen is the most abundant compound found in the air. It accounts for about 78% of the air that we breath. It is closely followed by oxygen that accounts for about 21% of the air.

Answer:

They will die off too

Explanation:

The animals that feed off the rabbits will start to die off from starvation, and so will the animals tho eat off of those. The entire food chain above the rabbits will start to decrease, while the plants and animals that the rabbits eat will increase in population due to less predators.

Answer:

Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds. ... In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.

Answer:

Explanation:

Insulin is an hormone used to regulate blood glucose, as it helps to maintain a balance. It allows for transport of glucose to organs such as liver.

The process of glucose regulation is a complex process. When food is eating glucose is absorbed into the bloodstream this happen from the gut and it raises the blood glucose level this causes insulin(hormone) to be released from the pancreas so glucose can move inside the cells and be used.

As glucose moves inside the cells, the glucose level inside the bloodstream returns to normal and insulin release slows down.

Glucose which is the main energy source used by cells is allowed to be taken up by muscles, liver and fat (adipose tissue) and use as a source of energy so they can function properly.

Answer:

The Rutherford atomic model stated that an atom is mostly an empty space that consist of nucleus and electrons, where nucleus is positively charged and electrons are negatively charged.

But Rutherford atomic model missed to add the quantum mechanics or energy level for electrons. Rutherford was unable to make understand the planetary movement of electrons around nucleus and later Bohr's model explained it.

Hence,  Rutherford's model of the atom missed to explain the planetary movement of electrons around nucleus.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

N[tex]_2[/tex] + 3H[tex]_2[/tex]  [tex]\rightarrow[/tex] 2NH[tex]_3[/tex]

moles of N[tex]_2[/tex]= given number of molecules/ 6.022×10²³

                  = 2 x 0²³/ 6.022×10²³

                  = 0.33 moles

moles of NH[tex]_3[/tex] produced= moles of N[tex]_2[/tex]×2

                                      =0.66moles

mass of NH[tex]_3[/tex]= moles of NH[tex]_3[/tex]×Molar mass of NH[tex]_3[/tex]

                    =  0.66 × 17.03

                    =11.23 g

Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.

HYBRIDIZATION:

Answer:

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory

Answer:

Molecular formula is, C₃H₆O₃

Empirical formula (with the lowest subscript) → CH₂O

Explanation:

We assume that the organic acid's mass is 0.6 g. We know that, in 0.6 g of compound we have 0.24 g of C and 0.04 g of H, then, we have

(0.6 - 0.24 - 0.04) = 0.32 g of O.

We determine each mol:

0.24 g /12 g/mol = 0.02 mol of C

0.04 g/ 1g/mol = 0.04 mol of H

0.32 g/ 16 g/mol = 0.02 mol of O

1 mol of acid weighs 90 g/mol.

In 0.6 g of acid, we have, (0.6 g / 90g/mol) = 0.0067 moles

Let's find out the formula with rules of three:

0.00667 mol of acid have 0.02 moles of C

1 mol of acid may have (0.02 /0.00667) = 3 mol of C

0.00667 mol of acid have 0.04 moles of H

1 mol of acid may have (0.04 /0.00667) =  6 mol of H

0.00667 mol of acid have 0.02 moles of O

1 mol of acid may have (0.02 /0.00667) = 3 mol of O

Molecular formula is, C₃H₆O₃

We confirm by the molar mass: 12g/mol . 3 + 6 . 1g/mol + 32g/mol . 3 = 90

Empirical formula (with the lowest subscript) → CH₂O
