As you approach the surface of the sphere very closely, the electric field should resemble more and more the electric field from an infinite plane of charge.
If you check Gauss's law (recalling that the field in the conductor is zero) you will see that if the surface charge density is σ=Q/4πR2, then indeed the field at the surface is σ/ϵ0 as in the infinite charge of plane case.
Such a field is constant, the field lines are parallel and non-diverging, and the infinities associated with the field due to point charge do not arise.
Explanation:
We know that V=E/Q Where V is the PD, E is the energy, and Q is the charge.
Substituting in the values gives V=48/4=12
Therefore the PD across the circuit is 12V
Answer:
Nanotechnology
Explanation:
is this for that crossword puzzle lol
Answer:
Explanation:
The incident angle is 
so the reflected ray will also be .
The normal divides the angle between the incident and reflected ray. So, the angle between them would be
So, the angle between the incident and reflected rays is .
<h3># Question </h3>
Q1- the speed will increase because the particles will have more energy which causes them to move faster
Explanation:
<h3>With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. </h3>
