THE LIGHT BULB IS AN EXAMPLE OF -
-
CONDUCTION
-
RADIATION
-
ELECTROMAGNETIC
-
CONVENTION
Correct Answer
A. RADIATIONExplanation
The light bulb is an example of radiation because it emits light energy in the form of electromagnetic waves. Radiation is the transfer of energy through electromagnetic waves, and in the case of a light bulb, the energy is radiated outwards in the form of visible light. Conduction, convection, and electromagnetic are not suitable explanations in this context as they do not accurately describe the transfer of energy from a light bulb.Rate this question:

DEFINE CONDUCTION?
-
THE UP AND DOWN MOVEMENT OF GASES- LIQUID TRANSFERS TO HAET.
-
THE PRIMARY METHOD BY WHIC HEAT MOVES GASES THROUGH LIQUID.
-
HEAT TRANSFER TO AND THROUGH SOME MATERIALS.
-
TRANSFER OF HEAT BETWEEN SUBSTANCES THAT ARE IN DIRECT CONTACT WITH EACH OTHER .
Correct Answer
A. TRANSFER OF HEAT BETWEEN SUBSTANCES THAT ARE IN DIRECT CONTACT WITH EACH OTHER .Explanation
Conduction refers to the transfer of heat between substances that are in direct contact with each other. It occurs when heat energy is transferred from a region of higher temperature to a region of lower temperature through direct molecular collision. This process does not involve the movement of gases or liquids, nor is it specific to any particular material.Rate this question:

WHEN ELECTROMAGENTIC WAVES TRAVEL THROUGH THE SPACE WHAT THEY CALLED?
-
ELECTROMAGNETIC
-
CONVENTION
-
RADIATION
-
CONDUCTION
Correct Answer
A. RADIATIONExplanation
Electromagnetic waves are called radiation when they travel through space. This term refers to the process of energy transfer through the emission of electromagnetic waves, such as light, radio waves, and X-rays. Radiation is different from conduction, which involves the transfer of heat or energy through direct contact, and from convection, which involves the transfer of heat through the movement of a fluid. Therefore, radiation is the correct term to describe the travel of electromagnetic waves through space.Rate this question:

WHERE DO ELECTROMAGNETIC WAVES TRAVEL THROUGHT?
-
EVERYWHERE
-
ALL THE SPACE
-
EMPTY SPACE
-
ALL THE ABOVE
Correct Answer
A. EMPTY SPACEExplanation
Electromagnetic waves are able to travel through empty space because they do not require a medium, such as air or water, to propagate. Unlike mechanical waves, which need a material medium to travel through, electromagnetic waves consist of oscillating electric and magnetic fields that can exist and propagate in a vacuum. Therefore, electromagnetic waves can travel through empty space, making "empty space" the correct answer.Rate this question:

GIVE AN EXAMPLE OF CONVECTION?
-
A LIGHT BULB
-
HOT AIR BALLOON
-
A CAMP FIRE
-
A MICROWAVE OVEN
Correct Answer
A. HOT AIR BALLOONExplanation
A hot air balloon is an example of convection because it involves the transfer of heat through the movement of a fluid. In this case, the fluid is the air inside the balloon. The burner at the bottom of the balloon heats up the air, causing it to become less dense and rise. As the hot air rises, it carries the balloon and its passengers along with it. This process of heat transfer through the movement of a fluid is known as convection.Rate this question:

CONVENTION IS THE UP AND DOWN MOVEMENT OF GASES AND LIQIDS CAUSE BY -
-
HEAT TRANSFER
-
ELECTROMAGNETIC
-
TRANSFER THE HEAT TO THE OBJECT
Correct Answer
A. HEAT TRANSFERExplanation
The correct answer is "heat transfer" because convention refers to the movement of gases and liquids caused by heat transfer. Heat transfer is the process by which thermal energy is transferred from one object or substance to another. In this case, the up and down movement of gases and liquids is a result of the transfer of heat energy.Rate this question:

WHEN THE ELECTROMAGNETIC WAVES CONECT WITH THE OBJECT THE WAVES TRANSFER TO WHAT-
-
OBJECT
-
SPACE
-
WAVES
-
HEAT
Correct Answer
A. HEATExplanation
When electromagnetic waves connect with an object, they transfer their energy to the object. This energy is then converted into heat, causing the temperature of the object to increase. Therefore, the correct answer is "HEAT."Rate this question:
