So I'm trying to study for finals and I am stuck on a concept. Does anyone know how to relate a Transient Response of a first order system to the bandwidth of the filter?

Does the transient response fall faster for a higher bandwidth or something?

thanks

I have.....Electrons moving about a nucleus don't emit radiation because they form standing waves. Does this sound correct or is there some kind of principle to go along with it?

I know it sounds a LOT crazy, but just imagine Einstein in place of Newton......

Maybe Lord MC^2 would not have had gravity in his mind at all!!!! I just want ur opinion...Cheers!

Small coin is sliding inside a cone without friction. The axis
of the cone is vertical. Minimum distance from the tip of
the cone Dmin = 30cm, and maximum distance Dmax = 90cm.

What is average by time distance from the tip
of the cone to the coin?

[a] 50cm
[b] 55cm
[c] 60 cm
[d] 65 cm

I have read all the other answers explaining the equation and the measurment and description of how to measure gravity. But I have never heard a description of how or why it actually works. Why do objects with mass attract? Like the answer to, "How do cars stop?" would be expained by the friction caused by the brake pad rubbing on the rotor thus impeding it's ability to keep turning.
I have never heard a gravity explanation expaining "why" or how gravity works like it does. The closest I have heard is the Einstien theory about the dent in the fabric of space that causes a "dip" that other objects go towards....but is this accepted as fact? Also, why would an object with mass dent space and time?

If the explanation of how gravity works is that any object with mass attracts other objects with less mass, then why isn't a baseball attracted to a bowling ball?

Compare the performances of two clocks. The first clock is based on a single
pendulum, the second on a torsional pendulum. Assume that the clocks are calibrated
to show the correct time at a certain point. Compare the performances when the clock
are taken to a different environment where
a) The elevation is different
b) Humidity is different
c) Temperature is different

Many books and articles I have read try to describe the extra 6 curled up dimensions in string theory as "attached" or "existing on" every point in 3d space. The last time I read this was "the elegant universe" by Brian Greene. Well, if a point is merely a piece of information that is not actually a place or tangible thing, then how can dimensions exist on, near or within something that isn't there to begin with?
