Answer:
For low-mass stars, after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.

Find the midpoint between (0,0) and (-4,-12)
(29) and (5,1)
Answer:
-2, -6
[tex]\frac{7}{2}[/tex] , 5
Explanation:
Given coordinates;
(0,0) and (-4,-12)
(2, 9) and (5,1)
Unknown:
Midpoints of the coordinates = ?
Solution:
The coordinates of the midpoint are given as;
x[tex]_{m}[/tex] , y[tex]_{m}[/tex] =( [tex]\frac{x_{1} + x_{2} }{2}[/tex] , [tex]\frac{y_{1} + y_{2} }{2}[/tex])
Now;
x₁= 0 x₂ = -4 y₁ = 0 y₂ = -12
Input the parameters and solve;
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{0+(-4)}{2}[/tex] , [tex]\frac{0+ (-12)}{2}[/tex] = -2, -6
For (2, 9) and (5,1)
x₁= 2 x₂ = 5 y₁ = 9 y₂ = 1
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{2 + 5}{2}[/tex] , [tex]\frac{9 + 1}{2}[/tex] = [tex]\frac{7}{2}[/tex] , 5

What is the HELIOCENTRIC model of the solar system?
Answer:
The heliocentric model of the solar system is the one that suggests that the sun is in the center of the universe and everything revolves around it.
Explanation:
There have been few models throughout history when it comes to the arrangement and hierarchy of the objects in space. Most of them have been wrong, though they have persisted for a very long time. Some, like the heliocentric model, got some basics right, but it still had some mistakes which from today's perspective are big ones.
The heliocentric model suggests that the Sun is the center of the universe, with all other objects in space orbiting around it. Now, it did guess right that the planets in the solar system revolve around it and that it is in the center of it, but it made a big mistake by putting the Sun in the center of the universe, not just the solar system. Not just that the Sun is not in the center of the universe, it is not even close to the center of the galaxy in which it is, nor it is the largest object or the one with the biggest gravity so that it attracts everything around to revolve around it.

Which of the following regions can be defined by its physical boundaries?
A. O New England
B.
The Midwest
C
Colorado
D. Hawaii

what inferences can we make regarding earthquake magnitude, frequency, or concentration
Answer:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

A. Ice Melts and increases the ocean volume causing flooding
B. Ice seeps into the ground doubling the size of aquifers
C. Water dries out in certain regions but floods in others
D. Water evaporates into the atmosphere and returns as precipitation
Answer:
The manner in which the hydrologic cycle can be described in simple words is that the water evaporates into the atmosphere and returns as precipitation.
Explanation:
A is not correct because this describes the changes in the water bodies and their condition depending on the climate.
B is not correct because this describes how the ice influences the water bodies located underground.
C is not correct because this describes the distribution of water based on climate conditions.
D is correct because it describes the hydrologic cycle in a simple manner, with the water evaporating into the atmosphere, then it condensates when conditions form precipitation (rain, snow, hale) occurs and falls on the surface.
