A. push or pull

Explanation:

When you are applying force to an object, you can do so by pushing or pulling the object. Newtons first law applies to this. The object will stay at rest until a force is applied. The force can be pushing or pulling.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

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
