Tertiary sources summarize or synthesize the research in secondary sources. For example, textbooks and reference books are tertiary sources. Is interview primary source or secondary? Primary sources […]

How do you find the sum of forces? The net force is the vector sum of all the forces. That is, the net force is the resultant of all the forces; it is the result of adding all the forces together as vectors. For the situation of the three forces on the force board, the […]

Is Dark Matter growing? The total mass of dark matter is fixed, so as the Universe expands and the volume increases, the density of dark matter drops, just like it does for normal matter. As space expands, the dark energy density remains constant, rather than decreasing or increasing. Does observation affect reality? Summary: One of […]

Does higher electronegativity mean stronger bond? Generally, yes. A bigger difference in electronegativity indicates that the bond is more ionic. Since ionic bonds are known to have strong bonding characteristics, it makes sense that the more ionic a bond is, the stronger the bond. How does electronegativity affect melting point? As you must be knowing, […]

What happens when you walk 5 km a day? Improved capability to control body weight Walking for 30 minutes covers a distance of 2.0 to 2.5 km and burns about 125 calories (520 kiloJoules). This amount may not seem like much, but if you walked five days a week within one year you would burn […]
