What is C in binding energy? 12 C. This is the mass of the carbon atom, i.e. the mass of the nucleus plus the six electrons in the neutral carbon atom. Let’s calculate its binding energy. Why heavy nuclei are unstable? The presence of too many protons and neutrons in heavier nuclei will upset the […]
How many years did it take to form the first galaxy?
What happens if an enzyme is altered?
What happens if an enzyme is altered? If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature. How does an enzyme speed up a reaction? Enzymes are biological catalysts. […]
Can variable names start with a capital letter?
Can variable names start with a capital letter? Variable names always begin with a lowercase letter. If a name consists of multiple words, the first letter of all words except the first is capitalized, for example, endOfLineMarker , totalBill . Although legal, variable names never contain the underscore (unless they are constants) or the dollar […]
Is electric potential zero when electric field is zero?
Is electric potential zero when electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Where is the electric potential zero? The electric potential from […]
What is leading reactive power?
What is leading reactive power? A leading power factor signifies that the load is capacitive, as the load “supplies” reactive power, and therefore the reactive component Q is negative as reactive power is being supplied to the circuit. For which load reactive power is negative? In a R+1/(jwC) load (AC)voltage lags current with θ degrees. […]
What is meant by static pressure?
What is meant by static pressure? : the force per unit area that is exerted by a fluid upon a surface at rest relative to the fluid. What is another name for static pressure? Static pressure in fluid statics The term (hydro)static pressure is sometimes used in fluid statics to refer to the pressure of […]
What is the minimum energy needed to ionize hydrogen atom when it is in the N 2 state?
What is the minimum energy needed to ionize hydrogen atom when it is in the N 2 state? Minimum energy needed to ionize an electron from 2nd Bohr orbit of hydrogen atom is 5.45×10−19 J/atom. How much energy would it take to remove an electron from hydrogen? For a hydrogen atom, composed of an orbiting […]
What is it called when you avoid a question?
What is it called when you avoid a question? Question dodging is a rhetorical technique involving the intentional avoidance of answering a question. This can lead the person questioned to be accused of “dodging the question”. In the context of political discourse, evasion is a technique of equivocation that is important for face management. What […]
What are called P block elements?
What are called P block elements? The p-block elements are found on the right side of the periodic table. They include the boron, carbon, nitrogen, oxygen and flourine families in addition to the noble gases. So when I say p-Block elements I mean all those guys off to the right side of the periodic table […]
