What is the use of reverse bias? A reverse bias reinforces the potential barrier and impedes the flow of charge carriers. In contrast, a forward bias weakens the potential barrier, thus allowing current to flow more easily across the junction. What happens in reverse bias? By applying a negative voltage (reverse bias) results in the […]

What are 2 key features of an experiment? In an experiment, an independent variable (the cause) is manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. An advantage is that experiments should be objective. The views and opinions of the researcher should not affect the results of a study. How […]

Is Apple an oligopoly? Big Tech. Operating systems for smartphones and computers provide excellent examples of oligopolies in big tech. Apple iOS and Google Android dominate smartphone operating systems, while computer operating systems are overshadowed by Apple and Microsoft Windows. Are cars an oligopoly? The US automobile industry is a good example of an oligopoly. […]

Can I sell biogas? Making business out of Biogas: You could sell it at Rs 20/Ltr and he would need atleast 20 Ltr. That would make it Rs 20×20 Ltr = Rs400 per person. If you can sell it to 10 people every day that would make it Rs 4,000 per day. That would make […]

What is the range of energies for secondary electrons? Secondary electrons are generally considered to have energies below 50 eV. The rate of energy loss for electron scattering is very low, so most electrons released have energies peaking below 5 eV(Seiler, 1983). How secondary electrons are formed? Secondary electrons (SE) are produced when an incident […]

What is an example of chemical weathering by water? Chemical Weathering From Water Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. What are the […]

Can I put my hand through a wall? You could move an object through a wall without having enough energy to embed it inside a wall. But you can’t do that with just your hand, since your arm would have to be in the wall. Also, while it does get to the other side of […]

Are there 5 or 6 kingdoms? Until recently the system devised by Robert Whittaker in 1968 was widely adopted. Whittaker’s classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. What are the 3 main domains of life? According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. […]
