An elliptic analog bandpass filter is to be designed with the following specifications passband edge: 30 khz and 50 khz stopband edge: 25 khz and 55 khz peak passband ripple: 0.25db minimum stopband attenuation: 40db what's the bandedge of the corresponding elliptic analog low-pass filter? (note: there are two possible solutions but you only have to provide one) (5pts) what's the filter order of the corresponding elliptic analog low-pass filter? (you can use matlab to get your answer. however, you need to include your code to receive full credit) (5pts)

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
