Answer: The distance between particles, and the amount of electric charge they carry.
Explanation:
Charles Coulomb wanted to figure out the strength of the force between two objects and these were the two most independent factors.
First of all, I is proportional V according to the Ohm's Law. R is merely a constant you need to obtain an equation. However, it is true that R changes with temperature and pressure, therefore Ohm's Law is only applicable in an invariable environment. Also this constant R is different for different materials.
So, do not get confused.
Ohm's law is not a universal law, please remember that as well. Some materials do not follow it and we call them non-ohmic conductors. I hope I helped! ^-^
there were different outcomes each time.
Mantle convection
Explanation:
The driver of moving plates is the mantle convection.
Convection is a heat transfer process that involves the movement of fluids from one place to another.
How does convection occur in the mantle?
- Part of the mantle known as the asthenosphere is a hot liquid. It moves slowly and does not readily flow.
- Over riding the asthenosphere is the brittle lithosphere made up of the upper mantle and the entirety of the crust.
- The asthenosphere is at a higher temperature compared to the lithosphere on top.
- In order to achieve stability and thermal equilibrium, the asthenosphere rises to the surface whereas the dense and cold lithosphere sinks down.
- This way a convective cell is set up.
- Hot materials rises to the surface because they are light whereas cold materials on the surface sinks into the asthenosphere.
- Through this the plates moves.

Answer:
In most materials, as heat energy is absorbed, the density decreases. IF a certain object is heated, it might appear bigger than usual because it expands as the molecules inside moves faster than usual. However the mass of it stays the same while the density decreases.
