The invention of the _____________ was considered the critical invention for easily classifying and organizing Stars by brightness, color, and temperature


Radio Telescope


HR Chart (Hertzsprung- Russell)


Infra red Camera

Nasa Star Modeling Programs

Answers

Answer 1

Answer:

radio telescope

Explanation:

We use radio telescopes to study naturally occurring radio light from stars, galaxies, black holes, and other astronomical objects. We can also use them to transmit and reflect radio light off of planetary bodies in our solar system.

Answer 2
not a telescope, thats how you see stars. the answer is the HR Chart. If you look at this chart, it has all of the types of stars organized by brightness, color, and temp like the question asks.

Earth’s surface is constantly changed by erosion and deposition. Erosion breaks down Earth’s surface by carrying materials away from an area. Deposition builds up Earth’s surface when these materials are deposited in an area over time.

volcanic soil
cinder cone
caldera
lava plateau

Answers

Answer:

Caldera

Explanation:

C

The  landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform is caldera.

Where does the operation take place?

Involving the wear, transport and deposition of soils and rock particles. Erosion is the process of wear, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents, such as water, wind and living beings.

In this case the caldera is  landform results when erosion occurs during volcanic eruptions, but deposition does not directly contribute to creating the landform.

What happens to the motion of an object if forces acting on the object are equal and balanced?

A. The object begins to move

B. The object begins to slow down

C. The motion of the object does not change

Answers

Answer:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.

So I think its C

You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

Answers

Explanation:

need points bye have good day

Answer:

CH4+2O2→CO2+2H2O

Explanation:

Start with the least common atoms and leave things like H and O to the end.

You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.

Hope this is useful.

If two people attempt the same maneuver, what determines the amount of force that each is required to exert?

Answers

Answer:

Explanation:

you need to change either the turn of the jump or push off higher or lower from the wall

If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.

The amount of force exerted by each person is given by Newton's second law of motion, which states that the force exerted by an object is directly the proportional to the product of mass and acceleration of the object.

F = ma

where;

F is the applied forcem is the mass of the objecta is the acceleration of the object

Thus, If the two individuals start at the same position and time, the amount of force exerted by each person is determined by mass of the person.

What is electromagnetic spectrum?

The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
