Is a lit match a catalyst? Enzymes are catalysts. They speed up the rate of a chemical reaction by reducing the activation energy, which is the energy needed to carry out the reaction. An example of a catalyst: if you put a lit match to a sugar cube, it’s hard to make the sugar catch […]
What is the advantage of a larger telescope?
What is the advantage of a larger telescope? As the light collecting area of a light bucket is proportional to the diameter squared, doubling the diameter of the lens quadruples the light gathering power and thus greatly increases your ability to detect much fainter objects. The bigger the aperture, the more powerful the telescope. Is […]
What does it mean when pickups are out of phase?
What does it mean when pickups are out of phase? When they are out-of-phase, the two pickups work against one another; the resulting sound is simply the “leftovers” from the pickups’ cancellations. The closer the two pickups are, the greater the cancellations, meaning thinner sound and lesser volume. How do you tell if a pickup […]

What is the pattern seen in the magnetic stripes on the seafloor?
What is the pattern seen in the magnetic stripes on the seafloor? A polarity reversal means that the magnetic North flips to where we know the South Pole is. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor […]

What is the source of energy generation in an AC generator?
What is the source of energy generation in an AC generator? The source of energy generation is the mechanical energy of rotation of armature coil. How do you calculate the emf of an AC generator? The induced emf in a coil in AC generator is given as: E=NABωsinθ ω=dθ/dt. Now, when the angle between the […]
How do you find Thevenin resistance with dependent sources?
How do you find Thevenin resistance with dependent sources? Thevenin’s theorem can be applied when analyzing a circuit with dependent sources. In this case, all independent sources are turned off and the RTh is calculated by applying a current source or voltage source at the open terminal. When using a voltage source, it can be […]
