What will happen if two hydrogen atoms combine? Thus, two Hydrogen atoms combine to form a Hydrogen molecule. The number of protons in the atomic nucleus is equal to the number of electrons revolving around that nucleus. This means that the positive electric charge is balanced by the negative. The atom is therefore electrically neutral. […]

What is the working distance for a 10x objective lens? Table 2 – Long Working Distance Objectives Designation Magnification Working Distance ELWD 100x 2.0 mm SLWD 10x 20.3 mm SLWD 20x 20.5 mm SLWD 50x 13.8 mm What happens if you try to use the coarse adjustment when the 10X lens? What happens if you […]

At what speed do airbags become ineffective? For unbelted occupants the effectiveness goes to zero or becomes negative above 40 kph (25 mph) for MAIS 3+, and for belted occupants the effectiveness stays positive but with significantly lower magnitude for speeds above 40 kph (25 mph). What if my airbags didn’t deploy? If your airbag […]

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? The presence of hydrogen and helium in very high amount leads the sun to be the only source of heat and light for all planets as hydrogen and helium being a light element do nuclear fusion to form enormous energy with production of heat and light. What […]

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? 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 […]

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? 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 […]
