Homework Statement
Calculate "f" and its uncertainty, watch the units, show all work.
Homework Equations
f(x,z)= z/x
x=100.5(+ or -) 3.8 cm
y=71(+ or -) 1 s
The Attempt at a Solution
ok so i know that to find uncertainty i have to use the equation delta f(x,y)=df(x,y)/dx *(delta x) + df(x,y)/dy * delta y. I got (delta f)= z*lnx*(delta x) + (delta z)/x. When i plug in the numbers the units don't match up, i get cm*s + s/cm.
im really confused on how to find the answer can someone please help. thanks.
