KonstantinChe [14]3 years ago
5 0

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

(C) infrared

(D) visible light

(E) gamma ray

(F) x-ray

(G) ultraviolet

Which triangles are congruent according to the sas criterion?.
julia-pushkina [17]

<u>SAS Criterion:</u> If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

From the diagram you can see that:

<A ≅ <F ≅ <P

AB ≅ GF ≅ PQ

AC ≅ FE ≅ PR

This means that ΔABC, ΔFGE, and ΔPQR are congruent.

the volumes of two similar solids are 210 m3 and 1,680 m3. the surface area of the larger solid is 856 m2. what is the surface a
kolezko [41]

The surface area of the smaller solid is found to be 214 square meters.

<h3>What is Surface area?</h3>

The surface area is given as the sum of the area of all the faces of a three-dimensional object.

The same shape has equivalent ratio of the surface area to volume. It is given as:

\rm \dfrac{\sqrt{area_1}}{\sqrt{area_2}}=\dfrac{\sqrt[3]{Volume_1} }{\sqrt[3]{Volume_2} }

On considering the power of 6 at both the sides of the equation:

\rm \dfrac{area_1^2}{area_2^2}=\dfrac{volume_1}{volume_2}

Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:

\rm\dfrac{(856\;m^2)^3}{(area_^2)^3}=\dfrac{(1680\;m^3)^2}{(210\;m^3)^2}

By solving the above equation, the area of the smaller solid is found as 214 square meters. Thus, option B is correct.
