In house wiring, three colored wires are typically used: Live (or Phase): Usually red or brown, carries current to the appliance. Neutral: Usually blue or black, completes the circuit. Earth (Ground): Usually green or green/yellow, provides a path for electrical ...
A curved mirror, whether concave or convex, has a focal point where parallel rays either converge (concave) or diverge (convex). This point, called the focal point, is crucial in understanding image formation and optical properties of curved mirrors.
Thermit process is a metallurgical reaction where a mixture of aluminum powder and a metal oxide, typically iron oxide, undergoes an exothermic reaction, producing molten metal and heat.
When light passes through a prism, it undergoes refraction, separating into its component colors due to varying speeds in the different wavelengths. This dispersion reveals the spectrum, showcasing distinct hues.
Oxygen in human blood is vital for cellular respiration, generating energy for body functions. It sustains life, supporting metabolic processes and ensuring organs and tissues receive the necessary oxygen for optimal functioning.
Liver disease encompasses various conditions affecting the liver’s structure or function, often caused by infections, alcohol misuse, fatty liver, or autoimmune disorders. Symptoms may include jaundice, fatigue, and abdominal pain.
Control and coordination are essential physiological processes in living organisms. They ensure harmonized functioning of body systems through nervous and endocrine systems, maintaining homeostasis and enabling responses to stimuli.
Resistivity is a material property measuring its inherent opposition to electric current flow. It is quantified in ohm-meters (Ω·m) and depends on a substance’s composition and temperature.
When an electric current flows through a circular loop of wire, it generates a magnetic field. This phenomenon is fundamental to electromagnetism and finds applications in devices like solenoids and transformers.
