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 […]

Do charges move quickly through empty wires? It’s a common misconception that charges slow down as they go through the filament of a bulb because the filament is thinner than the wires in the rest of the circuit. Animation showing that the current is the same even if the wires have different thicknesses because the […]

Is 0 a rational number? Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer. Is negative […]

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 , […]

How can heat pumps be more than 100 efficient? By contrast, heat pumps seemingly undertake the impossible: you get more heating out than the energy you put in. This is possible because we are using energy to move heat – rather than converting the energy directly to heat. As a result the apparent efficiency in […]

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 […]

How do humans get nitrogen for fertilizer? So they get the nitrogen they need from the soil where bacteria have converted it into a usable form. To grow more crops, people have been transforming nitrogen from the atmosphere into nitrogen fertilizers and then adding the fertilizers to the plants. What is nitrogen cycle diagram? The […]
