Electric Discharge and Friction

What causes the electric discharge between the body and the sweater?

• Magnetic field

• Chemical reaction

• Exchange of electrons during friction

• Static electricity

What form of energy is released during the electric discharge?

• Electrical energy

• Thermal energy

• Kinetic energy

• Potential energy

What is the result of the energy release during the electric discharge?

• Emission of magnetic and gravitational waves

• Production of water and air

• Creation of solid and liquid

• Production of light, heat, and sound

Why does a crackling sound occur during the electric discharge?

• Rapid expansion and contraction of air

• Friction between two surfaces

• Static electricity buildup

• Presence of water vapor in the air

What is the role of friction in the electric discharge?

• Reducing static electricity

• Preventing the generation of electricity

• Generating static electricity

• Attracting electricity from the environment

How does the electric discharge between the body and the sweater occur?

• The electric discharge occurs due to the heat generated between the body and the sweater.

• Electrons are transferred from one to the other, causing an imbalance of charge and resulting in an electric discharge.

• Protons are transferred from one to the other, causing an imbalance of charge and resulting in an electric discharge.

• The body and the sweater repel each other, causing an electric discharge.

What happens to the energy released during the electric discharge?

• It is converted into mechanical energy

• It is absorbed by the surrounding materials

• It disappears without any effect

• It is released in the form of light, heat, and sound.

What is the significance of the crackling sound during the electric discharge?

• The crackling sound is caused by the rapid expansion and contraction of air due to the heat produced by the electric current.

• The crackling sound is a sign of impending thunderstorm

• The crackling sound is a result of the electric current being too weak

• The crackling sound is caused by the presence of tiny insects in the air

Explain the relationship between electric discharge and friction.

• Electric discharge is caused by gravitational force.

• Friction has no impact on electric discharge.

• Friction can cause electric discharge to occur.

• Electric discharge can prevent friction from occurring.

Describe the process of electric discharge between the body and the sweater.

• Static electricity is transferred between the body and the sweater through friction, leading to electric discharge.

• The body and the sweater attract each other, causing electric discharge

• The body and the sweater repel each other, causing electric discharge

• Electric discharge occurs when the body and the sweater are in close proximity
