All metal atoms have mobile electrons, making them good conductors of heat. Heat is transferred as the free electons at the end that's being heated, rapidly move from atom to atom in the metallic bonds. This rapid movement of electrons allows for the transfer of heat energy from one end of the rod to the other.
<span>B. interstellar dust
Condensation theory states that the solar system was formed due to the condensation of interstellar dust coming from a solar nebula.</span>
Resistance = (voltage) / (current)
= (12 v) / (2 A) = 6 ohms .
