The magnitude of the attractive force between two ions, a2+ and b2- at equilibrium is 5.6e-9 n. determine (a) the interionic distance, (b) the ionic radius of b2- if that for a2+ is 0.239239 nanometers, (c) the magnitude of the repulsive force between the two ions at this position, (d) the value of the coulomb's constant b and (e) the minimum potential energy of the bond. assume n = 7 in coulomb's law. don't forget ! (a) interionic distance: (b) ionic radius of b: (c) magnitude of force (d) coulomb's b: (e) emin

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
