D. Electromagnetic waves
<span><span> Generally, Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase.</span><span>The creation of all electromagnetic waves usually begins with a charged particle, which creates oscillating electric and magnetic fields.</span><span>Once they are in motion, the electric and magnetic fields that are charged in particles creates are self-perpetuating: time-dependent change in one field (electric or magnetic) to produce the other.</span></span>
<span>An
atom with an atomic number of 12 has 12 protons. Because the mass
number is the sum of the protons and neutrons, the mass number would
need to be at least 12. I hope this helped!

Because of the Earth's revolution, a solar day is slightly longer than a sidereal day. In every day life, we use solar time. The Earth must rotate an extra 0.986 degrees between solar crossings of the meridian. Therefore in 24 hours of solar time, the Earth rotates 360.986 degrees.
