Determine the magnitude ratio of signals with frequencies of one-half the corner frequency, equal to the corner frequency, and twice the corner frequency for both first-order and second-order butterworth low-pass filters. tabulate these values for easy comparison and discuss the effect that filter order has on a filter being able to reject noise while maintaining the signal, especially when the signal frequency and noise frequency are relatively close to each other.

Try b? sorry if i’m incorrect

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
