Why is the Buckingham π theorem used? Significance. The Buckingham π theorem provides a method for computing sets of dimensionless parameters from given variables, even if the form of the equation remains unknown. Most importantly, Buckingham’s theorem describes the relation between the number of variables and fundamental dimensions. What are repeating variables in Buckingham Pi […]
What are the 4 stages of drug development?
What are the 4 stages of drug development? Drug Development Phases Phase 1: Discovery and Development. Phase 2: Preclinical Research. Phase 3: Clinical Research. Phase 4: FDA Review. Phase 5: FDA Post-Market Safety Monitoring. What percentage of drugs get FDA approval? 9% Which drugs do not need an FDA approval? A few current (and some […]
Is km a unit of speed?
Is km a unit of speed? The kilometre per hour (SI symbol: km/h; abbreviations: kph, kmph, km/hr) is a unit of speed, expressing the number of kilometres travelled in one hour. Which is not unit of speed? Answer. Explanation: b cannot be the unit of speed. How many Kilometre make an hour? 120km What’s the […]
Which way does current flow?
Which way does current flow? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite […]
Is h20 dative covalent bond?
Is h20 dative covalent bond? H2O(l) + H+(aq) [H3O]+, a pair of electrons (a lone pair) from the oxygen atom of the water is donated to a proton to form an oxygen-hydrogen dative (co-ordinate) covalent bond in the oxonium ion. Is CO2 polar or nonpolar molecule? Polar molecules have a non-zero net dipole moment. Both […]
Why CSMA CA is used for wired network?
Why CSMA CA is used for wired network? CSMA/CA tries to reduce the frequency of these collisions and provide a plan at the same time on how to proceed if a collision does occur. The protocol is also important because the transmissions in the wireless networks cannot run in the same order (due to the […]
What is Isrelaxation time?
What is Isrelaxation time? Relaxation time is the time gap between two successive electron collisions in a conductor. The relationship between the relaxation time (T) and drift velocity (Vd) is given below. What is the symbol of relaxation time? (i) Relaxation time (τ): In the absence of an external electric field, the free electrons in […]
What type of reaction is copper II chloride?
What type of reaction is copper II chloride? Copper(II) chloride is a mild oxidant. It decomposes to copper(I) chloride and chlorine gas near 1000 °C: 2 CuCl2 → 2 CuCl + Cl. Copper(II) chloride (CuCl2) reacts with several metals to produce copper metal or copper(I) chloride (CuCl) with oxidation of the other metal. What is […]
What are examples of lab techniques?
What are examples of lab techniques? Blotting Techniques. Blotting is the most common lab technique widely used in the field of cell & molecular biology. Techniques For Extraction & Storage of Biomolecules. Gel Electrophoresis. Microscopic techniques. Polymerase Chain Reaction. Cell Culture Techniques. Spectroscopic Techniques. Chromatography Technique. What are basic lab skills? Essential Laboratory Skills A […]
What is a specular material?
What is a specular material? (of reflected light) directed, as from a smooth, polished surface (opposed to diffuse ). A specular surface is a highly smooth surface. When the surface is very smooth, the reflected highlight is easy to see. Why can’t you see your image on a concrete wall? Answer. Answer: You get diffuse […]
