How do you remove oxygen from water?
How do you remove oxygen from water? This is possible using a process known as electrolysis, which involves running a current through a water sample containing some soluble electrolyte. This breaks down the water into oxygen and hydrogen, which are released separately at the two electrodes. Why mnso4 is added in dissolved oxygen water sample? […]

What happens when PN junction is reverse biased?
What happens when PN junction is reverse biased? A forward bias diminishes the potential barrier, thus allowing current to flow effortlessly across the junction. In contrast, a reverse bias reinforces the potential barrier and impedes the flow of charge carriers. What is forward bias in PN junction? Forward bias occurs when a voltage is applied […]
How do you find the binding energy of lithium?
How do you find the binding energy of lithium? If we find the mass defect, i.e. how much less mass the nuclide has compared to the expected mass of the protons + neutrons, then it turns out that mass incorporated into E=mc2 gives the binding energy. Md=(mp+mn)−(mexact−me) , where: Md is the mass defect in […]
How do you change the amplitude of a sine wave?
How do you change the amplitude of a sine wave? Multiplying a sine or cosine function by a constant changes the graph of the parent function; specifically, you change the amplitude of the graph. When measuring the height of a graph, you measure the distance between the maximum crest and the minimum wave. What is […]

What are the two main points of cell theory?
What are the two main points of cell theory? The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. Who found […]
