<span>Electric
current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. The answer is c. Typically, incandescent light bulb consists
of a glass enclosure that contains tungsten filament. The glass enclosure contains
either a vacuum or an inert gas that serves as the filament protection from
evaporating. Incandescent light bulbs contain a stem attached at to its base to
allow the electrical contacts to run through the envelope without gas or air
leaks</span>
Answer:
B
Explanation:
did this yesterday with my friend
1. Magnetic properties of a substance depends on the structure of its valence electrons. It has something to do with orbitals so I suggest you study about molecular geometry of a compound/substance firstIt's the way a substance's atoms fit together, being pulled and pushed from all sides equally. exists in metallic bonds <span>if a substance is said to be magnetic, it is simply attracted by a magnet. if it is paramagnetic, it is repelled by a magnet.
2.</span>The magnetic field will be perpendicular to the electric field and vice versa<span>
An electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge.
A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.
The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.
The electrostatic force between charged particles is an example of this relationship.</span>
