Two positive point charges q are held fixed on the x-axis at x=a and x= –a. a third positive point charge q, with mass m, is placed on the x-axis away from the origin at a coordinate x such that /x/< < a. the charge q, which is free to move along the x-axis, is then released. find the frequency of oscillation of the charge q. (hint: when the restoring force is directly proportional to the displacement from equilibrium, the oscillation is called simple harmonic motion. use the binomial expansion \left( {1 + z} \right)^n = 1 + nz + n\left( {n - 1} \right)z^2 /2 + ; ), valid for the case \left| z \right| < 1.) express your answer in terms of the variables q, q, m, a and appropriate constants.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
