Considering the definition of wavelenght, frecuency and propagation speed, the frequency of the electromagnetic radiation that has a wavelength of 720.0 nm is 4.167×10¹⁴ Hz.
In a periodic wave the wavelength (λ) is the physical distance between two points from which the wave repeats itself. It is expressed in units of length (m).
The frequency (f) is a measure of the number of cycles or repetitions of the wave per unit of time. Its unit is s⁻¹ or hertz (Hz).
The propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave's disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:
v = f×λ
In this case, you know:
v=c= 3×10⁸ m/sf= ?λ= 720 nm= 720×10⁻⁹ mReplacing in the definition of propagation speed:
3×10⁸ m/s= f × 720×10⁻⁹ m
Solving:
3×10⁸ m/s÷ 720×10⁻⁹ m= f
4.167×10¹⁴ Hz= f
Finally, the frequency of the electromagnetic radiation that has a wavelength of 720.0 nm is 4.167×10¹⁴ Hz.

when attempting to control someone or something, do people compromise their own freedom in the process?
Perception differs for a lot of people. I believe that attempting to control someone or something, will not make one compromise their own freedom in the process.
Why attempt to control someone if you are going to loose your right to do whatever you want or be free. One's aim to control is to be able to do what you want.Freedom is the right of an individual to be free and even though it can be compromised by the evil intensions of other people, it is not right to so it to yourself. Lossing your freedom over something is not worth it. Though some people do compromise their freedom for anything but not in all situations.So therefore, I believe that people do not compromise their freedom at all and Lost of freedom is not what a person desires.

What is the chemical formula for nickel (III) oxide? NiO Ni3O NiO3 Ni2O3
The chemical formula for Nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex].
Given data:
The chemical formula for nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex]. This formula indicates that each molecule of nickel (III) oxide consists of two nickel (Ni) atoms and three oxygen (O) atoms.
Nickel is in its +3 oxidation state. The oxidation state represents the charge of the element in the compound, and in nickel (III) oxide, each nickel atom carries a +3 charge.
The presence of three oxygen atoms in the compound is indicated by the subscript 3 after the O in the formula. This means that there are three oxygen atoms for every two nickel atoms in the compound.
Hence, the chemical formula [tex]Ni_{2}O_{3}[/tex] represents nickel (III) oxide.

What is the first step of performing CPR on infants after you have checked for consciousness and breathing? shake, stroke, or tap the baby immediately call 911 give deep, strong compressions deliver gentle rescue breaths to protect the baby’s lungs
The first step of performing CPR on infants after you have checked for consciousness and breathing is: D. deliver gentle rescue breaths to protect the baby’s lungs
CPR is an acronym for cardiopulmonary resuscitation and it can be defined as an act performed by professionals or experts, in order to revive a patient whose respiratory system is failing.
Basically, cardiopulmonary resuscitation (CPR) should typically be performed for patients who are still consciousness and breathing because they still have life in them.
The cardiopulmonary resuscitation (CPR) performed on infants is quite different from that being performed an adults because infants are fragile and have less developed organs.
During CPR, an infant's chest should be compressed lightly and a shallow rescue breathing given to him or her.
In conclusion, the first step of performing CPR on infants after checking that he or she is consciousness and breathing is to deliver gentle (shallow) rescue breaths to protect the baby’s lungs.

natural steroids are compounds that mimic the steroids that human bodies naturally produce, such as the hormones testosterone, progesterone, and cortisol
Explanation:
They are safe substitutes for anabolic is true about natural steroids. Hence, option B is correct.
What is meant by natural steroids?Natural steroids, which can be found in plants, herbs, and other natural sources, are chemicals that resemble human hormones or steroids. In the body, natural steroid proponents claim their medications behave similarly to anabolic steroids. These are compounds that help to increase testosterone synthesis and support the development and repair of muscle.
The natural steroid hormones are normally produced from cholesterol by the gonads and adrenal glands. The hormones in these forms are lipids.
A number of physiological functions, including the immune system's response to stress, the metabolism of proteins and carbohydrates, blood electrolyte levels, the regulation of inflammation, and behavior, are influenced by natural steroids.

why do scientists observe blueshift in certain stars?
The Doppler effect allows finding the answer for the blue shift of some stars is:
The star closing in on us
The Doppler effect is the change in the frequency perceived by the relative movement of the emission and the receiver, in the case of light we must use relativistic relations and the expression is
[tex]f = f_o \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
Where f and fo are the observed and emitted frequencies, respectively, c the speed of light and v the relative speed between the source and the observer, this speed is positive if they move away and negative if they approach.
The speed light is related to frequency and wavelength
c = λ f
[tex]f = \frac{c}{ \lambda}[/tex]
we substitute
[tex]\frac{1}{\lambda } = \frac{1}{lam_o } \ \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
[tex]\lambda = \lambda_o \ \sqrt{ \frac{1+ \beta }{1- \beta } }[/tex]
with [tex]\beta = \frac{v}{c}[/tex]
The magnitude of β is always less than 1
Let's analyze the effect of the speed between the observer and the emitter on the perceived wavelength, we have two:
The two bodies are moving away, in this case the velocity is positive, let's substitute[tex]\lambda_1 = \lambda_0 \ \sqrt{\frac{1+| \beta|}{1- |\beta|} }[/tex]
We can see that the numbering of the root increases and the dominated decreases, so the root increases its value, consequently
[tex]\lambda_1 > \lambda_o[/tex]
This process is called redshift.
The two bodies are approaching, in this case the velocity is negative, we substitute
[tex]\lambda_2 = \lambda_o \ \sqrt{\frac{1- |\beta| }{1+ |\beta| } }[/tex]
We see that the root decreases its value, consequently
[tex]\lambda_2 < \lambda_o[/tex]
This is called the blueshift.
In this exercise, indicate that we have a blueshift, which is why the star is approaching us.
In conclusion, using the Doppler effect we can find the answer for the blue shift of some stars is:
The star closing in on us

which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism? select all that apply.
Answer:
Explanation:
Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.
Osmosis is transport in which the movement of a solvent occurs through a semipermeable membrane from a less concentrated solution into a more concentrated one without any protein.
Diffusion is a process where the molecule moves from one part to another part through the membrane.
Diffusion and osmosis are types of passive transport that do not require energy
This kind of movement does not involve transport proteins or other complex mechanisms.
Large polar molecules like glucose, amino acids, ions move through a membrane with the help of proteins
small non-polar molecules such as oxygen, carbon dioxide by diffusion and small polar molecules like water
large non-polar molecules like lipids can cross the membrane without the help of proteins by osmosis.
Thus, Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.
