Explanation:
The relation between potential difference, current and resistance flowing in a circuit is given by using Ohm's law. It can be given by :
V = IR

Resistance opposes the flow of electric current in the circuit. It means that, if resistance is more, less current will flow through the circuit.
The density of the glass can be determined using the formula:
- Density of the glass = (Mf - Mi)/20 cm³
<h3>What is density?</h3>
Density is defined as the ratio of mass and volume of a substance.
The mass of the glass = Final mass of beaker - initial mass of beaker (Mf - Mi)
The initial mass of the beaker is not given.
Volume of the glass marble = 20 cm³
Density of the glass = (Mf - Mi)/20 cm³
Therefore, the density of the glass is determined from the ratio of the mass and volume of the glass.

Answer:
Answer would be C because combustion does the process of heat. Oxygen is a reactant in a combination reaction, which always produces energy in the form of heat and light. Carbon burns in the presence of oxygen to give carbon dioxide.
False, it does create pollution form the smoke stacks and after the process is done they have barrels of toxic waste
