The movement of a fluid during convection is a circular/oval motion since the fluid at the top sinks and the fluid at the bottom rises.
Hope this helps :)
Answer:
The distance that you marginally able to discern that there are two headlights rather than a single light source is 6.084 km
Explanation:
Given:
d = distance = 0.679 m
λ = wavelength of the light = 537 nm = 537x10⁻⁹m
dp = pupil diameter = 4.81 mm = 0.00481 m
Question: What distance, in kilometers, are you marginally able to discern that there are two headlights rather than a single light source, dx = ?
For the separation of the peak from the central maximum it is:
In this case, the two small sources of the headlights have the same angle as the images that form inside the eye
Answer:
Aristotle
Explanation:
In ancient Greece, the popular
philosopher Aristotle declared
that all matter was made of only
four elements: fire, air, water
and earth. He also believed that
matter had just four properties:
hot, cold, dry and wet.
<span>The correct answer to
the question that is stated above is letter d. Luminosity.
</span><span>Luminosity is the total energy that star produce in one second, depending on both the radius of the star and on its surface temperature. Thus, </span><span>all the star's properties such as its temperature, size, brightness and life span is determined by its luminosity.</span>
The answer is <span>B. the amount of hot soup contained in a bowl. Buoyancy is defined as the upward force exerted by a fluid on an object immersed in that fluid. Buoyancy and density are two factors that affect the downward and upward forces exerted on object that affect its ability to "float" or "sink". Only B does not have anything to do with such forces.</span>
