Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field.

Explanation:

In other word, EM waves are composed of oscillating magnetic and electric fields. They are also perpendicular to the direction of the EM wave. It can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples : radio wave, microwave,X-rays etc

Hope this will work to u

come closer and become far apart and become steam/gas

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
