Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
Que se conserva en el choque elastico?
¿Que se conserva en el choque elastico? En física se dice que el choque entre dos o más cuerpos es elástico cuando se conserva la energía cinética total del sistema de cuerpos durante la interacción. ¿Qué efecto produce la energía cinetica en un choque? Colisiones. Si el choque es perfectamente inelástico (plástico) la energía cinética […]
How are potential and distance related?
How are potential and distance related? Moving towards and away from the charge results in change of potential; the relationship between distance and potential is inverse. For one point charge, potential will be constant for all points a certain radial distance away. Multiple points of the same potential are known as equipotential. How do you […]

How do you know if alkene is symmetrical?
How do you know if alkene is symmetrical? A symmetrical alkene is an alkene in whose molecule the doubly bonded carbons bear the same ligands. eg. 1: In 1, each double bonded carbon bears two methyl groups. How do you identify asymmetric carbon? A carbon atom is asymmetric if it has four different chemical groups […]
What is the difference between indication and contraindication?
What is the difference between indication and contraindication? In medicine, a contraindication is a condition that serves as a reason to not take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. What are contraindications […]
What are the 3 level of awareness?
What are the 3 level of awareness? The three levels of awareness in human consciousness which are divided by Freud: the conscious, preconscious, and unconscious. Each of these levels interferes and overlaps with Freud’s ideas of the id, ego, and superego. What are 4 levels of consciousness? Take a look at the four levels of […]
Is gold a good heat reflector?
Is gold a good heat reflector? Surfaces designed to reflect a broad spectrum of electro-magentic waves, (shiny things generally, like mirrors or polished metal) specifically infrared wavelengths are good reflectors of radiant heat. Gold is the best material for reflecting radiant heat. Does gold Harden work? Heat: In general, Yellow Gold can be hardened by […]
