Two protons are separated by a distance of 3.8 x 10−8 m in air. Find the magnitude of electric force and determine whether it is repulsive or attractive?

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

I'd go for the one that says that knees are fulcrums, lower legs are levers and the ankles hold loads.hope it ,happy homework/ study/ exam!
