The frequency and energy ranges of photons in some parts of the electromagnetic spectrum are given in the table above. Which of the following could be the energy of a photon in the visible range?.
Answers
Answer:
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.
The energy of photon in visible range will be of [tex]4 \times 10^{-19} J[/tex].
What is the electromagnetic spectrum?Violet, indigo, blue, green, yellow, orange, and red are hues in the electromagnetic spectrum. Blue light has a very short wavelength and hence creates more energy.
Blue light in the visible zone has a very short wavelength. So that it produces a higher amount of energy that's why the blue part of visible light transfers the most energy.
The photons in the infrared range have the lowest energy and photons in the ultraviolet range have the highest energy.
A photon in the visible range should have an energy which is between the infrared range and the ultraviolet range.
Wherever the maximum energy of a photon in the infrared range is 3 x 10-19 J and the minimum energy of a photon in the ultraviolet range is 5 x 10-19 J,
Thus, photon in the visible range could have an energy of [tex]4 \times 10^{-19} J[/tex].

An entrepreneur is considering the purchase of a coin-operated laundry. The current owner claims that over the past 5 years, the mean daily revenue was $6750 with a population standard deviation of $265. A sample of randomly selected 30 days reveals a daily mean revenue of $6280. If you were to test the null hypothesis that the daily mean revenue was $6750, which test would you use?.
Answers
Based on the given value of sample size and the population standard deviation, the required test for the null hypothesis is the Z test of population mean.
The Z test of population is used to test the null hypothesis of a Normal distribution. Since, the sample size is large (>30) and the variance of the population is known, the most appropriate test of hypothesis to use is the Z test of population mean.Learn more : https://brainly.com/question/25576166

What is a chemical reaction?A chemical reaction is a transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances.
When a chemical reaction occurs, the reactance responds by rupturing the bonds in the energy and forming new compounds. Breaking chemical bonds between reactant molecules (particles) and creating new bonds between atoms in product particles are two aspects of chemical reactions (molecules).
Therefore, the correct option is A, Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants.

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In the diagram,
⇒ CE = 12 units
⇒ BE = 5 units
Now,
Since, Triangle CBE is an right triangle.
And, We have;
⇒ CB = AB
⇒ ∠DBC = 90°
⇒ ∠ABE = ∠DBC = 90° (opposite angles formed by the intersection of AC and DE.)
As, ∠CBE and ∠ABE are supplementary angles and form a straight line.
So, We get;
⇒ ∠CBE + ∠ABE =180°
⇒∠CBE = 180° - ∠ABE
= 180°- 90°
= 90°
And, Between triangle ΔCBE & ΔABE;
⇒ ∠CBE = ∠ABE = 90°
⇒ CB = AB (given)
⇒ BE = BE (common side)
Hence, The triangles Δ CBE & ΔABE are congruent.
⇒ Δ CBE ≅ ΔABE( by S-A-S Congruency)
⇒ CE = AE ( as triangle Δ CBE & ΔABE are congruent then the sides are same.)
⇒ AE = 12 units
Thus, The length of AE = 12 units
