"what is straight? a line can be straight, or a street, but the human heart, oh, no, it's curved like a road through mountains." meaning

maybe this is trying to say that the human heart is unique its beautiful and different with all its curves its beautiful

and with the straight lines its not different bc it will always be never changing.

hope this helps and maybe makes sense.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

because if the tool that you are using is not balanced it there would be false mass.
