This is not a very good set of choices.\

ANY type of electromagnetic wave can be used to send information from place to place, IF we can set up the following conditions:

-- We can only use the electromagnetic waves that are not dangerous to be around.

-- We also can't use the ones that can be blocked or degraded by natural things, like rain, fog, or smoke.  

-- We need an easy way to generate them whenever we want them.

-- We need an easy way to change something about them in a pattern that carries the information.

-- We need an easy way to detect them.

-- We need an easy way to accurately detect the changes, so that we can pull the information off of them.

The electromagnetic waves that DO meet all of those requirements, and we DO use to communicate information are:

-- Radio

-- Microwave

-- Infra-red

-- Visible light

(We use visible light to transmit information when we send it through an optical fiber, and also when we wave at our friend across the street !)

I have an astronomy question... Spinning up the solar nebula. The orbital speed of the material in the solar nebula at Pluto's a
attashe74 [19]
<span>The angular momentum of a particle in orbit is 

l = m v r 

Assuming that no torques act and that angular momentum is conserved then if we compare two epochs "1" and "2" 

m_1 v_1 r_1 = m_2 v_2 r_2 

Assuming that the mass did not change, conservation of angular momentum demands that 

v_1 r_1 = v_2 r_2 

or 

v1 = v_2 (r_2/r_1) 

Setting r_1 = 40,000 AU and v_2 = 5 km/s and r_2 = 39 AU (appropriate for Pluto's orbit) we have 

v_2 = 5 km/s (39 AU /40,000 AU) = 4.875E-3 km/s

Therefore, </span> the orbital speed of this material when it was 40,000 AU from the sun is <span>4.875E-3 km/s.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

shutvik [7]
"Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution."
