Does benzene absorb UV light? Note that both benzene and naphthacene absorb light in the near ultraviolet but that the latter does so much more intensely. A solution of naphthacene will absorb almost 100 times as much light at 250 nm. as a solution of benzene of the same molar concentration. Can light break bonds? […]

How is a floodplain formed? Floodplains are formed through erosion which happens when a river constantly thrashes its sides, widening its own length. Furthermore, floodplains are a part of scenic beauty. How meanders are formed? The formation of a meander. As the river erodes laterally, to the right side then the left side, it forms […]

Why H2O is polar and CO2 is nonpolar? Both CO2 and H2O have two polar bonds. However the dipoles in the linear CO2 molecule cancel each other out, meaning that the CO2 molecule is non-polar. The polar bonds in the bent H2O molecule result in a net dipole moment, so H2O is polar. Which is […]

What does Div F mean? We also have a physical interpretation of the divergence. If we again think of →F as the velocity field of a flowing fluid then div→F div F → represents the net rate of change of the mass of the fluid flowing from the point (x,y,z) ( x , y , […]

Both plant and animal kingdoms are subdivided into […]

What would happen if there was no moon? The moon affects the angle of the Earth’s tilt. The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days.

Is steel easy to bend? Most steel bars are either hot-rolled or cold-rolled; a cold rolled bar is shinier than a hot rolled bar, but is also harder to bend. Stainless steel is even harder to bend. The stronger the steel, the more the bend will approximate a “V”, while the weaker the steel, the […]
