Depends. Are you talking about a mathematical 4th dimension (in which there is infinite dimensions) or some sort of etheral dimension (in which there is no scientific evidence for)
If you mean the first then yes. But it depends how these beings exist. From our understanding we only can theorize shapes in 4-d and if we assume that there is only one universe these "beings" arleady exist and thus any message in 3-d would be sent to them like a shadow ("flat").
If they exist in a alternate "plane" then you would need some method to transverse this plan and if u did, then we would easily be able to communicate, but we would at first sound like a wild animal. They either would ignore us, not understand or perceive us, or they would attempt to send back a signal (essential they are ET's)
IF you mean the second then thats some mystic stuff and its pretty creepy (although a fun read for me :P)

Neutral Magnesium atom
Explanation:
From the given description of the atom, one can infer that this atom is a neutral atom.
In a neutral atom, the number of protons and neutrons are the same.
Atomic number = 12
Mass number = 25
This atom is Magnesium.
Magnesium has an atomic number of 12 from the periodic table.
Number of protons = 12 = atomic number
Number of electrons = 12(for neutral atoms, atomic number is same as number of electrons).
Number of neutrons = mass number - atomic number = 25-12 = 13.

Answer:
Light comes in different colors like radio, ultra violet, gamma-ray, etc, and they are invisible to the bare eye
Explanation:
Prevailing definitions of climate are not much different from “the climate is what you expect, the weather is what you get”. Using a variety of sources including reanalyses and paleo data, and aided by notions and analysis techniques from Nonlinear Geophysics, we argue that this dictum is fundamentally wrong. <span>In addition to the weather and climate, there is a qualitatively distinct intermediate regime extending over a factor of ≈ 1000 in scale.Climate changes is projected to affect individual organisms, populations, ... Overall, there is a strong correlation between topographic slope and velocity from ... the ecosystems they live in—will adapt to these changes, or if they even can.</span>
Explanation:
The work done by an object is given by :
Here,
F is force
d is displacement
is the angel between F and d.
If the angle between force and displacement is 0, then the work done is equal to, 
.
So, a force does work on an object if a component of the force is parallel to the displacement of the object.
