Answer: The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a resistor. Electricity travels easily and efficiently through a conductor, with almost no other energy released as it passes.
Explanation:
C. Mechanical, because temperature can cause solid objects to expand and contract, causing rocks to split apart.
Because polymers are covalently bonded material, and metals are metalicly bonded material.
Covalent bonds do not let atoms exchange electrons like metalic bonds do.
Ocean currents are formed by a type of heat transfer that is convection

Hi myself Shrushtee.
Explanation:
The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.
