Draw Lewis structures to determine which of the following
compounds exhibit resonance. Enter the letters corresponding to all
those compounds which exhibit resonance. (If you find that choices
A, C, and F all have resonance and the others do not, for example,
you would enter ACF as your answer. Make sure the letters you enter
are in alphabetical order, with no spaces or commas separating
them.)

2 criticalF m 2m2 A) For a frictionless system, resonance occurs when the system is driven at the natural frequency wo vk/m. If we take the friction out of the spring-mass system. we're studying, we have m 1 and k 26 still. Calculate the natural frequency of this frictionless system, compare it to the critical driving frequency for the system with friction included, and draw a conclusion about the effect of friction on the frequency at which resonance occurs.
