Homework Statement
determin the dimensions of [tex]\alpha[/tex] in the following
a)Sin([tex]\alpha[/tex]X[tex]^{}2[/tex]) (alpha* X squared) (X is a distance)
b)10[tex]\alpha[/tex]t3
c)cot([tex]\alpha[/tex]X2/R) (R is a radius)
d)e(hf/[tex]\alpha[/tex]T - 1 (h is Plancks constant with units J*s) ( f is frequency
Homework Equations
The Attempt at a Solution
so are these all supposed to be dimensionless?
attempt at a: [L2 [tex]\alpha[/tex] ] = 1 therefore [tex]\alpha[/tex]= [1/L2 ] (where L is length)
id appreciate some help :)
