Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

I know that I'm late but, the correct answer is:
The Earth's outer crust (the lithosphere) is composed of a series of tectonic plates that move on a hot flowing mantle layer called the asthenosphere. Heat within the asthenosphere creates convection currents that cause tectonic plates to move several centimeters per year relative to each other.
the formula to find force is F=ma
F- Force (in newtons)
m- mass (in kg)
a- acceleration (in m/s)
in this case you need to find acceleration, so isolate a by making the formula a=f/m. plug in your numbers then you're done
a=30/70
a=0.429 (rounded)
