Answer:

Option (3)

Explanation:

Given that, planet Y is at a distance of 1 AU away from the sun, and the planet Z is at a distance 0.39 AU away from the sun.

From Kepler's law of astronomical unit, it is known that the planets that are closer to the sun move at a faster rate in comparison to the distant planets because of their high gravitational force.

So from the given condition, it can be concluded that the planet Y is at a greater distance (1 AU) from the sun, which will orbit the sun at a much slower rate because of its comparatively weaker gravitational force, as the speed of a planet is directly affected by the distance from the sun.

Thus, the correct answer is option (3).

The answer to your question is C: Planet Y, because the Gravitational force is weakened by the distance. Hope this helps!

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

? how does the zeitgeist affect the evolution of a science?

mel-nik [20]

Compare the growth of a science with the evolution of a living species. Zeitgeist is the intellectual and cultural climate spirit of a time. It means that a certain scientific discovery can be discarded or shunned because it is ahead of its time or maybe, because people are not willing to accept it.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X

weeeeeb [17]

Answer:

The observed image will not be sharp

Explanation:

When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).
