What is the energy of a wave having a frequency of 5.71 x 1013 Hz?
Answer:
[tex] \huge{3.783 \times {10}^{ - 19} \: J}[/tex]
Explanation:
The energy of the wave can be found by using the formula
E = hfwhere
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question we have
E = 6.626 × 10-³⁴ × 5.71 × 10¹³
We have the final answer as
[tex]3.783 \times {10}^{ - 19} \: J[/tex]

Copper has a density of 8.96 g/cm^3. What is the mass of a piece of copper with a volume of 2.62 cm^3?
Answer:
23.48
Explanation:
Good Luck!
Answer: 23.48 g
Explanation:
formula: mass = density x volume
Volume of copper = 2.62 cm^3
Density of copper = 8.96 g/cm^3
mass = 8.96 x 2.62 = 23.4752
Which of the following is an oxidation-reduction reaction? Fe2O3 3CO Right arrow. 2Fe 3CO2 CuSO4 2NaOH Right arrow. Cu(OH)2 Na2SO4 2NaOH H2CO3 Right arrow. Na2CO3 2NaOH Pb(NO3)2 Na2SO4 Right arrow. 2NaNO3 PbSO4.
The reaction, Fe2O3 + 3CO------> 2Fe + 3CO2 is an oxidation-reduction reaction.
An oxidation-reduction reaction is a reaction in which there is a change in oxidation number from left to right in the reaction. This is because, a specie is oxidized and another specie is reduced.
In the reaction; Fe2O3 + 3CO------> 2Fe + 3CO2, we can see that the oxidation number of iron decreased from +3 on the left hand side to zero on the right hand side. The oxidation number of carbon was increased from + 2 to +4.

The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply.
A) The females will equally choose the brightly colored and white peacocks as mates.
B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates.
C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce.
D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to be selectively bred for their unique trait.
E) The peacocks with colored tails will be picked over the white peacocks as mates, causing the peacocks with the white mutation to die out of the population over time
Leucism is a genetic mutation caused by an alteration of a nucleotide. The less brightly colored tails of the peacock will have less chance to mate.
What is selection?Selection is the natural process in which the organism with better trait quality is preferred and selected over another species. They are fit to survive in an altered condition.
The genetic mutation can lead to speciation and selection of the fittest organisms. The type of behavior selection results in the preference of the partners based on the mating and reproducing capabilities.
Therefore, option C. the peacock without impressive tails will be less likely to mate and reproduce.

Redox reactions involve one substance losing electrons (oxidized) and another substance gaining electrons (reduced) in the same reaction. As electrons are transferred between substances, the electrons lose potential energy and energy is released.
What is the relationship between layering of fluids and density?
Density of a liquid determines how it will layer (heaviest to lightest). If the liquid is least dense it will float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.
How can one determine if a compound is ionic or covalent?
Answer:
If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.

A) antigens present on the invaders
Explanation:
Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens

The amount of energy involved when an electron is acquired by a neutral gaseous atom is what?
Look at the diagram below. What type of bond does it show?
Explanation:
it shows covalent bonds
The type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.
What are bonds?Bonds are defined as any of the interactions that lead to atoms joining together to form molecules, ions, crystals, and other stable species that make up the familiar materials found in everyday life. The ability to build molecules is made possible by a chemical bond, which is a strong attraction between atoms, ions, or molecules. Chemical bonds that hold molecules together also form temporary connections vital for life.
Covalent bond are defined as a type of chemical link where atoms share electrons to create electron pairs. Low melting and boiling temperatures, low vaporization heat, low water solubility, and poor conductivity are four characteristics of covalent compounds.
Thus, the type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.

A. 1.1x10^-10 g
B. 2.5x10^-10 g
C 1.3x10^-10 g
D. 5.0x10^-10 g
The amount remaining at the end of 5 half-lives is 7.81×10¹³ g
From the question given above, the following data were obtained:
Half-life (t½) = 5730 yearsOriginal amount (N₀) = 2.5×10¹⁵ gNumber of half-lives (n) = 5Amount remaining (N) =?The amount remaining can be obtained as follow:
N = 1/2ⁿ × N₀
N = 1/2⁵ × 2.5×10¹⁵
N = 1/32 × 2.5×10¹⁵
N = 0.03125 × 2.5×10¹⁵
