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)

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
