Well, basically both Cheryl and Keaton is right.
matter is described as Physical substance that possessed space and mass.
But the thing is, one matter is very small in size and cannot be seen with naked eyes. But everything around us are made by matters
hope this helps
The mass of an object is the quantity of matter it possesses. The important thing to remember about mass is that it is constant, and therefore if you are on Earth, the Moon, Mars, or anywhere, your mass is always going to be the same.
Answer:
<em>Vernal equinox, autumnal equinox, march equinox, September equinox, northward equinox and southward equinox </em><em>are the names for the equinoxes.
</em>
<u>Explanation:
</u>
There are different names which are named depending on the <em>month of the year when these equinox occurs and depends upon direction of motion of the sun</em>.<em> Equinox is a point where day time and night time have exactly equal length of time.</em>
Equinox occurs <em>twice</em> in a year and this occurs when <em>earth's equator passes through the sun</em>. We can say that equinox occurs when the sun’s center is directly above the equator.
Answer:
I₂ = I₀ 1/4
Explanation:
For this exercise we use the definition of intensity which is the power per unit area
I = P / A
The emitted power is constant, so
P = I A
We can write this equation for the start and end point with index 2
I₀ A₀ = I₂ A₂
I₂ = I₀ A₀ / A₂
The spot area is the area of the circle
A₀ = π r₀²
We substitute
I₂ = I₀ r₀² / r₂²
It indicates that the radius of the spot is twice the initial radius
r₂ = 2 r₀
I₂ = I₀ (r₀ / 2 r₀)²
I₂ = I₀ 1/4
Answer:
1.The Sun is located at one of the foci of the planets' elliptical orbits.
2.The path of the planets around the Sun is elliptical in shape.
Explanation:
As per Kepler's law of planet motion we know that all planets revolve around the sun in elliptical path in such a way that position of Sun must be at one of the focii of the path
So all planets are in elliptical path always
Position of sun is always at one of the focus
so correct answer will be
1.The Sun is located at one of the foci of the planets' elliptical orbits.
2.The path of the planets around the Sun is elliptical in shape.
