if you put something like apiece of cardboard between a magnet and a iron nail, the magnet still holds the nail. how?
AlekseyPX
Magnetic fields can go through some materials (like cardboard). Electric fields can also do that. Electromagnetic waves can do that. It’s not at all unusual because magnetic fields are not made up of particles so they can go through materials.

Which list places the layers of the sun in the correct order from innermost to outermost?
LiRa [457]

Answer:

Convective zone, chromosphere, corona

Explanation:

A star like the Sun is divided into different layers according to pressure, density, temperature, and the mechanics of energy transport (in the case of the convective zone and radiative zone) for each of those layers.

In stars, there is an equilibrium between two forces, the force of gravity in the inward direction due to their own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in their core, that is known as hydrostatic equilibrium.

That leads to different layers according with the properties described above.    

       

Near the core, in the Sun, there is a radiative zone since radiation is the best mechanism of energy transport in this area. Then, in the next layer, it can be found that convection becomes a more efficient way of energy transport that radiation due to the fact that the inner part of the convection zone is at a greater temperature than the outer one.    

Finally, there is the atmosphere of the Sun (chromosphere, photosphere, and corona).

                                       

Key terms:        

Convection: Transport of energy due to different in density and temperature of a material (liquid, gas).

For the "what is this investigation about", you could pick
the shape of the Earth, the size of the Earth, how the Sun
generates its energy, the distance to the Moon, why the 
sky is blue ... things like that.  There are millions uvum.

Trustworthy sources of information:

-- a library book that's all about the subject of the investigation
-- a magazine that's all about exactly the subject of the investigation
