The region of the spectrum that best corresponds to light with a wavelength equal to;

1) The diameter of a hydrogen atom is; X-ray

2) The width of your pinky finger; microwaves.

3) The size of a virus; X-ray and Ultraviolet rays.

<h3>Electromagnetic spectrum</h3>

From online tables, the diameter of an hydrogen atom is approximately 1 × 10^(-10) m but according to electromagnetic spectrum, any wavelength between 10^(-8) m and 10^(-12) m is an x-ray.

From online tables, width of your pinky finger is 1.06 × 10^(-2) m but according to the electromagnetic spectrum the range between 1 and 10^(-3) m corresponds to microwave.

The size of a virus has the range from 2 × 10^(-9) m to 4 × 10^(-7) m. This Range falls into x-ray or ultraviolet rays.

The complete question is;

What region of the spectrum best corresponds to light with a wavelength equal to:

(1) the diameter of a hydrogen atom

(2) the width of your pinky finger

(3) the size of a virus

Choices:

(A) radio

(B) mircowave

(D) visible light

(E) gamma ray

(F) x-ray

(G) ultraviolet

An ellipse is represented by the equation . each directrix of this ellipse is a ________________________ from the center on the

Anastasy [175]

The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.

<h3>How to determine the distance of the directrix?</h3>

The equation of the ellipse is given as:

$\frac{(x - 5)^2}{625} -\frac{(y - 4)^2}{225} =1$

The above means that:

a^2 = 625

a = 25

b^2 = 225

b = 15

Calculate c using:

c^2 = a^2 - b^2

This gives

c^2 = 625 - 225

Evaluate the difference

c^2 = 400

Evaluate the square root

c = 20

The equation of the directrix is

x - x₀ = ± a²/c

So, we have:

x - x₀ = ± 625/20

Evaluate the quotient

x - x₀ = ± 31.25

This means that, each directrix is 31.25 units from the center on the major axis.

C. She felt she needed to save money.

D. She may have misunderstood her basic homeowners policy.

E. Her expenses were already high before paying for insurance.

According to the question, Maggie did not have enough money. She already had more than enough expenses.

The passage also said that there were months that the amount that she had was hardly enough to take care of basic needs.

She did not understand the home owners policy because she was told that they would offer it to her at an additional cost. She may have thought that she already had it covered.

Shalnov [3]

Problem recognition is the process the consumer becomes aware of a gap between their existing situation and the desired or ideal situation. This is further explained below.

<h3>What is Problem recognition?</h3>

Generally, Problem identification is the first step of the business buying process, and it occurs when someone within the firm identifies a problem or a need that can be addressed by purchasing a product or a service. This stage may also be referred to as "need recognition."

In conclusion, The process by which a customer becomes aware of a gap between their current position and the scenario that they want or consider to be ideal is known as problem recognition.
