What happens when a substance undergoes thermal expansion? Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms. Which expands the greatest when heated at the same […]
What is the formula for dynamic resistance?
What is the formula for dynamic resistance? The diode has the following characteristics: threshold voltage V0 = 0.6 V, forward dynamic resistance Rd = 0 and infinite reverse resistance. How do you calculate dynamic resistance on a graph? The slope of the graph between current and voltage in a p-n junction diode, under both forward […]
What is maximum absorbance wavelength?
What is maximum absorbance wavelength? The absorption is highest at around 510 nm (the wavelength at which absorption reaches its peak is called absorption maximum wavelength). How do you find the concentration of a solution in Class 9? The concentration of solution formula is given as follows. Cor S = Weight of solute in gramsVolume […]
What amino acid does AAU code for?
What amino acid does AAU code for? Amino acids Symbols Codons Asparagine Asn AAC, AAU Proline Pro CCA, CCC, CCG, CCU Glutamine Gln CAA, CAG Arginine Arg AGA, AGG, CGA, CGC, CGG, CGU What type of bond holds amino acids together? Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming […]
What are the 3 methods of pest control?
What are the 3 methods of pest control? Now, let’s see how these pest control methods are used. Physical methods of pest control. This is one of the natural methods of pest control; it is a non-chemical pest control method. Chemical methods of pest control. Cultural methods of pest control. Biological methods of pest control. […]
What is the rarest color of zircon?
What is the rarest color of zircon? Green Which Zircon is best? E.g. – A person weighing 60 kgs can wear a 6-carat Zircon gemstone. A highly transparent, colorless natural Zircon is preferred for astrological purposes. Silver or platinum is considered, the best. Alternatively, panchdhaatu, gold or white gold can also be used. Who should […]
Can a DC motor run on AC?
Can a DC motor run on AC? The AC series motor you describe is a universal motor, and will work fine on DC. The speed characteristics will be a little different, since when running on AC there’s a significant reactive drop in the field windings that reduces the available driving emf. Can you charge DC […]
Did Antarctica used to be hot?
Did Antarctica used to be hot? Climate change Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from 1957 to 2006. Did […]
What happens during the formation of a solution?
What happens during the formation of a solution? In order to form a solution, the solute must be surrounded, or solvated, by the solvent. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds. What are the factors affecting solution? Factors affecting solubility Temperature. Basically, solubility increases with […]
What is the relationship between transmitted and absorbed light?
What is the relationship between transmitted and absorbed light? The relationship between absorbance and transmittance is illustrated in the following diagram: So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption […]
