<span>The answer is letter D.

The most important step in formulation a scientific inquiry is to first formulate a question. All answers sprung from a question that scratched the mind. Experimentation is not possible without the need to question, with this, the drive to find the answers is what motivates scientists or people involved in an experiment to find the answers that would suffice their curiosity. Questions are the basis of all the other choices above and is the most crucial step in the scientific inquiry.<span>

Answer: c. choosing variables and controls.

A scientific inquiry is a fact finding inquiry regarding scientific reasons for natural phenomena. A scientific inquiry process involves development of questions, experimentation and drawing conclusion. The experimentation step of scientific inquiry involves choosing of variables and controls to derive data which can lead to conclusion of the scientific inquiry.

Please help!!! give me a summary on why human population is either good or bad!! thank youu

bagirrra123 [75]

It is bad because humans are destroying the planet with pollution and cutting down natural habitats. This is not only killing the human population in the future, but as of right now they are killing animals, and trees. The human population is slowly destroying the planet.

A speaker is designed for wide dispersion for a high frequency sound. What should the diameter of the circular opening be in a s

Greeley [361]

Answer:

$a = 4.76 cm$

Explanation:

As we know by the law of diffraction through circular aperture

$a sin\theta = 1.22 \lambda$

here we know that

a = diameter of the aperture

$\theta$ = diffraction angle

$\lambda$ = wavelength

now we have

$a = \frac{1.22 \lambda}{sin\theta}$

Now in order to find the wavelength we know

$\lambda = \frac{c}{f}$

$\lambda = \frac{343}{9100}$

$\lambda = 0.0376 m$

now we have

$a = \frac{1.22(0.0376)}{sin75}$

$a = \frac{0.046}{0.966}$

$a = 0.0476 m= 4.76 cm$

Alex777 [14]

Wavelength is represented by lambda( $\lambda$ )

$\\ \bull\tt\longmapsto \lambda=\dfrac{c}{v}$

C is speed of light in air.
v is the frequency.

It has unit as meter(m)

ANEK [815]

Answer:

A.model the reflection of a light wave

The Wave Model of Light Toolkit provides teachers with standards-based resources for designing lesson plans and units that pertain to such topics as the light's wavelike behaviors, wave-particle duality, light-wave interference, and light polarization

B. .model the absorption of a light wave

The simplest model is the Drude/Lorentz model, where the light wave makes charged particle oscillate while the particle is also being damped by a force of friction (damping force)

A mirror provides the foremost common model for reflective light wave reflection and generally consists of a glass sheet with a gold coating wherever the many reflections happen. Reflection is increased in metals by suppression of wave propagation on the far side their skin depths

C.model the transmimssion of a light wave

The Wave Model describes how light propagates in the same way as we model ocean waves moving through the water. By thinking of light as an oscillating wave, we can account for properties of light such as its wavelength and frequency. By including wavelength information, the Wave Model can be used to explain colors.
