What is the maximum age for height growth? Although most adults won’t grow taller after age 18 to 20, there are exceptions to this rule. First, the closure of the growth plates may be delayed in some individuals (36, 37). If the growth plates remain open past age 18 to 20, which is uncommon, height […]

What are the three main global wind belts?
What are the three main global wind belts? There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10). Fig. 3.10 only shows the circulation cells and winds in the Northern Hemisphere. What are the 2 main types of winds? Wind blowing above the […]
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 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 […]
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 […]
How do molecules bond with one another quizlet?
How do molecules bond with one another quizlet? A molecule is neutral group of atoms held together by covalent bonds. As atoms near each-other, the charged particles in their valence shells begin to interact. The positive nuclei and the negatively charged electrons in the outer shells are ATTRACTED to one another. What are the two […]
