Answer:
higher frequency waves will have more energy
Explanation:
Answer:
True
Explanation:
<em>Gas</em><em> </em><em>always</em><em> </em><em>live </em><em>in </em><em>free</em><em> </em><em>state </em><em>but </em><em>some </em><em>gas </em><em>is </em><em>not </em><em>.</em><em> </em><em>We </em><em>can </em><em>said</em><em> </em><em>that</em><em> </em><em>mostly</em><em> </em><em>gas </em><em>volume</em><em> </em><em>can </em><em>be </em><em>changeable </em><em>during</em><em> </em><em>disturbing</em><em> </em><em>by </em><em>environment </em><em>situation</em><em>.</em>
Matter can be many things, but is mostly made of atoms. Atoms are small things that cannot be seen directly, as lights either passes through it or alters it. However, we know that atoms are made of 3 parts, those being the proton, neutron, and electron.
Protons have a positive electromagnetic charge.
Neutrons have no charge.
Electrons have a negative charge equal to the protons positive charge.
Protons and neutrons make up what's called the nucleus, which is orbited by the electrons.
Protons and neutrons also share another thing in common, that being their composition.
Until relatively recently, we thought that these were the smallest particles in the universe, and indestructible. However, modern discoveries have revealed that they are actually made of quarks and gluons.
These are actually indestructible, being part of the group that is elementary particles.
Answer:
The correct statement is "The electric field is directed toward the electron and has a magnitude of 
".
Explanation:
According to Coulomb's law, the magnitude of the electric field due to a static point charge q at a point r distance away from it is given by
- k is the Coulmob's constant.
The direction of the electric field along the line joining the charge and the point where electric field is to be found and it is directed from positive charge to negative charge.
Conventionally, we assume a positive test charge placed at the point where electric field is to be found, the test charge has very small charge such that its charge does not affect the electric field due to the given charge.
The charge on the electron = -e.
The electric field due to an electron is given by
The direction of this electric field is from positive test charge, placed at the point where electric field is to be found, towards the electron along the line joining the two.
Thus, the correct statement is "The electric field is directed toward the electron and has a magnitude of ".
