Answer:
The speed of light in a vacuum is approximately 3 × 10^8 meters per second.

Question:
What is the principle of conservation of momentum?
Answer:
The principle of conservation of momentum states that the total momentum of a closed system is constant unless acted upon by an external force.

Question:
What is an example of a non-contact force?
Answer:
Gravity is an example of a non-contact force because it acts at a distance without any physical interaction.

Question:
What is the effect of temperature on resistance?
Answer:
As temperature increases, the resistance of most conductors increases.

Question:
What is the difference between conductors and insulators?
Answer:
Conductors allow the flow of electricity, while insulators do not allow electricity to pass through.

Question:
What is the formula for calculating the pressure exerted by a fluid?
Answer:
The formula for pressure in a fluid is P = F/A, where F is force and A is the area.

Question:
What is an ionic bond?
Answer:
An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, creating ions that are attracted to each other.

Question:
What is a covalent bond?
Answer:
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Question:
