The average salinity of sea water is
a. 3%
b. 3.5%
c. 2.5%
d. 2%

In terms of percent, the salinity of most sea water is between 2.5 and 4.5.

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

it is called kinetic energy
