A photon is a fundamental particle of light and electromagnetic radiation. It is the smallest discrete unit or quantum of electromagnetic energy. Photons are the carriers of the electromagnetic force
Mathematics is often referred to as the language of the universe. Its principles and concepts form the foundation upon which the physical sciences are built. From physics and chemistry to
Extraction of metals. Metal ores are naturally occurring rocks that contain metals or metal compounds in sufficient amounts to make it worthwhile extracting them.
The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving
Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different
The General Certificate of Secondary Education (GCSE) and the International General Certificate of Secondary Education (IGCSE) are two widely recognized qualifications for students aged 14 to 16. Both curricula cover
Electrical insulators, also known as dielectrics, are materials that do not conduct electricity well. They have high electrical resistance and are used to prevent the flow of electric current. Insulators
