The simple model below is a neutral magnesium (Mg) atom with the element’s most common mass number. A purple circle labeled M g sits at center with 3 concentric black lines around it. The inner line has 2 small green balls on it. The middle line has 8 small green balls on it. The outer line has 2 small green balls on it. What must happen to an atom of magnesium in order to become a magnesium ion Mg+2? It must lose two neutrons and become a different isotope. It must gain two neutrons and become a different isotope. It must lose two electrons and become an ion. It must gain two electrons and become an ion.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
