WILL GIVE BRAINLIEST PLEASE HELP! Please select the word from the list that best fits the definition stage in a star’s evolution formed as the core of a main sequence star uses up its helium and the outer layers escape into space

sorry I’m late
white dwarf is late stage in the life cycle of a comparatively low-mass main sequence star; formed when its core depletes its helium and its outer layers escape into space, leaving behind a hot, dense core. so the that would be the most reasonable answer thanks for posting, hope i helped

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

Answer:

The correct sequence according to the question is steps- 4→1→3→5→6→2→7.

Explanation:

The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as the rock cycle.

The steps of the rock cycle in sequence according to the question are:

1.  Breakdown of rock by weathering into regolith- step 4

2.  Dumping and deposition of regolith in a reservoir- step  1

3.  Erosion and transportation of regolith by rain or wind- step  3

4. Cementing of the deposited layer to form sedimentary rock- step  5

5. Conversion of sedimentary rock to a metamorphic rock due to intense heat and pressure- step 6

6. Conversion of  metamorphic rocks to magma due to the melting of metamorphic rocks-
step 2

7. Conversion of magma to igneous rocks due to volcanic activities and cooling of magma-  step 7

Therefore sequence according to the question is steps- 4→1→3→5→6→2→7 is correct.

The mountain shown is composed of deformed sedimentary layers. they are located near a tectonic plate boundary and are still increasing in elevation due to –

[ad_1]

The correct answer is – Andes Mountains.

The Andes Mountain Range is a result of a oceanic-continental convergence. This mountain range stretches alongside the western coast of the South American continent, in close proximity of the convergent boundary between the South American tectonic plate, which is continental one, and the Nazca tectonic plate, which is oceanic one.

The Nazca plate is subducting beneath the South American plate, and it managed to lift up the land in close proximity to the boundary. As the land was lifting up more and more, over time a mountain range was formed, the biggest and dominant one in South America, the Andean Mountain Range.

A clothing manufacturer uses lasers to cut patterns in fabric when making T-shirts. Which best describes a benefit of using lasers instead of traditional cutting machines? Laser machinery does not require energy. Laser machinery is safer because its light is weak. Lasers save time by cutting through more layers of fabric. Lasers result in fewer injuries because they quickly become blunt.

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

Which of the Earth’s layers is represented by the number two (2) on the image above? A. the mantle B. the outer core C. the inner core D. the crust

[ad_1]

The answer is plate tectonics theory.

The idea that earth’s lithosphere is divided into large, moving sections is called the Plate Tectonics Theory.

The Plate Tectonics Theory is not attributed to any single person or geologist. In fact, it developed over a number of years due to scientific exploration and the research of the Earth’s crust.

The theory explains how the Earth is divided into large sections of plates, that are always moving, leadint to changing shape of the landmass on Earth. The movement of these plates is what casues earthquakes.

It is based on the theory of continental drift and was widely accepted in the scientific community by the 1950s.

The first step is finding out what percentage of the first sample eat at school. Out of 60 students surveyed, 40 eat school lunch. To find that percentage:

40 / 60 = 0.67 or 67% (approximately) 

Now, we need to that that information and plug it into our problem. If we know 67% of kids eat school lunch, and 560 lunches were sold, we know that 560 is 67% of the school population. So now we must work backwards to find our answer.

To find out what 560 is 67% of, you will divide .67 by 560. This will get you approximately 836 < this is the number of students in total. 

Answer: You can predict there are around 836 students in the school. 

Whenever you work backwards like this, it’s always good to check your answer. We can do so by seeing what 67% of 836 is by multiplying the two. Once done, you should get 560.12, which verifies our answer is correct.

Sphere and right cyl. have the same radius and volume.  Thus, find the equations for the volumes of a sphere and a right cylinder and set them equal to one another:

Vol. of sphere       =       Vol. of right cyl.

  (4/3) pi r^3          =        pi r^2 * h

“pi” appears on both sides of this equation as “pi.”  So we can cancel “pi” from both sides.  We then have:

(4/3) r^3  =  r^2 h

Let’s now divide both sides of this new equation by r^2.  We then have:

(4/3) r = h

We must solve this for r in terms of h.  To do this, multiply both sides of this equation by (3/4).  This results in:

r = (3/4) h     This is the final answer:  the radius, r, in terms of the height, h.
