Why are electrons, rather than protons, the principal charge carriers in metal wires?

Physics

<span>because in any atom the electrons are in the outer orbitals while protons are within the nucleus together with the neutrons. If energy is supplied electrons can jump to higher energy levels and leave the lower orbitals. 
Especially in metals the conduction band is partially filled at room temperature with allows free flow of electrons throughout the metal thus they carry charge. 
(it requires huge amounts of energy to remove a proton from the nucleus such things happen on the surface of sun).</span><span>

vovangra [49]

Answer:

L = Pt/M

Explanation:

Power, P= Q/t = mL/t

​

we know that, (Q=m×l)

Now ⇒l= Pt/M

​

Thus l= Pt/M

Thomas Newcomen was the first to produce a working steam engine. Why is the work of James Watt more widely known than the work o
LenaWriter [7]

Answer:

The steam engine of James watt is more efficient than Newcomen ans more suitable for the industrial revolution.

Explanation:

James Watt is more widely know for working steam engine because Watt has created better engine which is suitable for the industrial revolution. The steam engine of James watt is more efficient than Newcomen. Watt developed the condensing arrangement by using piston which lessen the initial pressure leading to effectively worked than Newcomen's

Assignment: Can you identify various forces and instances in which electrostatic and magnetic forces occur​
serg [7]

Answer:

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
