yes
YES!!!!! As well as the pistons!
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
Your telling me!
fixed and floating charge
I live in Utah and I have found there is no difference
Potential difference.
current is the flow of charge.
The proton has a +1 charge, while a neutron has no charge, and is neutral.
Electrons have a negative charge and protons have a positive charge.
The potential difference between two points in a circuit is the energy required per unit charge to move a charge between those points. It represents the work done by an electric field on a charge as it moves through the circuit.
There is no difference, they are one the same. A proton has a positive charge and a positive charge is a proton. Of course with the positive charge, it's simply having more protons than electrons.
Nothing..
