What is the theoretical density of water? 0.99823 grams/cubic centimeter How do you increase the density of steel? When ingots are produced by the method of centrifugal casting, they are modified with dispersed WC and TiC particles, which increases the crystallization rate, increases the metal density, corrosion and mechanical properties. Does forging increase density? The […]
What will effect increasing the no of lines per cm?
What will effect increasing the no of lines per cm? Diffraction gratings are often identified by the number of lines per centimeter; gratings with more lines per centimeter are usually more useful because the greater the number of lines, the smaller the distance between the lines, and the greater the separation of images on the […]
Where is the action potential initially generated?
Where is the action potential initially generated? Membrane Potential and Action Potential Action potentials are typically initiated in the axon initial segment and the propagation of the action potential along the axon allows communication of the output of the cell to its distal synapses. What causes the repolarization phase of an action potential? Repolarization typically […]
What variable should be kept constant?
What variable should be kept constant? Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the […]
Which is better fabric softener or dryer sheets?
Which is better fabric softener or dryer sheets? Both fabric softeners and dryer sheets help eliminate static and wrinkles while making clothes feel softer and smell better. Dryer sheets reduce static and increase the cottony feel of fabrics. Dryer sheets are coated with stearic acid, which melts in the dryer and coats clothes to provide […]
What is difference between ionic compound and covalent compound?
What is difference between ionic compound and covalent compound? Ionic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons. 2. In an ionic compound, bonding involves a metal and nonmetal, whereas, in the covalent compound, bonding is between nonmetals. What is […]
Who disproved the idea of maggots spontaneously arising from rotten meat?
Who disproved the idea of maggots spontaneously arising from rotten meat? However, one of van Helmont’s contemporaries, Italian physician Francesco Redi (1626–1697), performed an experiment in 1668 that was one of the first to refute the idea that maggots (the larvae of flies) spontaneously generate on meat left out in the open air. Why do […]
Can nuclear power be used as a weapon?
Can nuclear power be used as a weapon? For example, the process of enriching uranium to make it into fuel for nuclear power stations is also used to make nuclear weapons. But there is always the danger that countries acquiring nuclear power technology may subvert its use to develop a nuclear weapons programme. Where is […]

How do you know the direction of propagation?
How do you know the direction of propagation? To find the direction of propagation of an E&M wave, point the fingers of the right hand in the direction of the electric field, curl them toward the direction of the magnetic field, and your thumb will point in the direction of propagation. What is the direction […]
