Check the dimensional validity ofthe EquationP = F + Av3p |
|
Answer» so the given P=FV+AV^3THE FORMULA FOR F= MLT^-2 (ma)V=LT^-1 (DISTANCE/TIME)a= l*b(L^2)A) THE DIMENSIONAL FORMULA OF POWER ISFORMULA =FORCE/AREASO MLT^-2/L^2 =ML^-1T^-2here if we want to add two variables SAY 3x +4x here only if x is the same variable we can add so the dimension of fv MUST be equal to av^3 suppose if they ask u 2 find the dimension of some constant by GIVING some equation plz keep ths idea in ur mindb) p=ML^-1T^-2 in Lhs and in rhsfv =( MLT^-2) (LT^-1)=ML^T^-3AV^3= (L^2) (LT^-1)^3=L^5T^-3so C here acc to the idea i said before only if de dimensions of all the 3 quantities we can say that they are dimensionally crt so here it is not dimensionally validExplanation:I hope it is help full for You |
