The universe contains
A. Few black holes
B. Billions of galaxies
C. Millions of stars
D. Few wavelengths

most of them using statistics and defining how things are being measured

the answer is a 3.8cm

explanation:

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

v=ir = 3x15 =45 v
