What is form according to Plato? In basic terms, Plato’s Theory of Forms asserts that the physical world is not really the ‘real’ world; instead, ultimate reality exists beyond our physical world. The Forms are abstract, perfect, unchanging concepts or ideals that transcend time and space; they exist in the Realm of Forms. Did Plato […]
Is the only source of heat and light?
Is sweating sympathetic or parasympathetic?
Is sweating sympathetic or parasympathetic? We need sweating to control body temperature; water evaporating from the skin cools the body. Sweating is under the control of the sympathetic nervous system, which orchestrates the body’s reaction to stressful situations and emergencies—sometimes called the “fight or flight” response. How do emotions affect the autonomic nervous system? The […]
Is heat needed in chemical change why?
Is heat needed in chemical change why? Chemical reactions involve the production of new materials which are quite different from the reacting substances. Any new materials come from the reacting substances. While heat is often necessary to initiate a chemical reaction it is not always necessary. Chemical reactions are used to produce most of our […]
Why do fizzy tablets dissolve faster in hot water?
Why do fizzy tablets dissolve faster in hot water? In the hot water the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move—and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction […]

What is the 7 Universal Laws?
What is the 7 Universal Laws? To name them, they are the Laws of Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect and Gender. Once you understand, apply and align yourself with these seven Universal Laws, you will experience transformation in every area of your life beyond what you have ever dared to imagine. What […]
What is the origin of frictional force?
What is the origin of frictional force? Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Friction originates in nanoscale contacts, as the result of new surface formation. The theory explains the generation of frictional force and frictional heating in dry contact. What energy does friction produce? When friction […]
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased?
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased? 4.As the electric current in a lightbulb is slowly increased, the filament glows more and more brightly. Why does this happen? As the current increases, the electrons more frequently bump into more atoms of the resistor (filament) […]
Which material has maximum value of thermal conductivity?
Which material has maximum value of thermal conductivity? Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer. Which material has least […]
