Adobe Connect Quiz Analyzer Excel - Free to Download

I'd like to share with you an Excel spread sheet that will help you analyze your Adobe Connect quiz reports. There are four worksheet tabs within the document: directions, question report data, answer report data, and a synthesized and processed results page.  Feel free to tweak and make it even better.  Undoubtedly I will be doing the same.  I have included an example that can be deleted out of the document before you use it.  Feedback welcomed.

Religion Forrest Church

Religion is our human response to the dual reality of being alive and having to die. Knowing we are going to die not only places an acknowledged limit upon our lives, it also gives a special intensity and poignancy to the time we are given to live and love. The fact that death is inevitable gives meaning to our love, for the more we love the more we risk losing. Love’s power comes in part from the courage required to give ourselves to that which is not ours to keep: our spouses, children, parents, dear and cherished friends, even life itself. It also comes from the faith required to sustain that courage, the faith that life, howsoever limited and mysterious, contains within its margins, often at their very edges, a meaning that is deceptive.

Why are there two tides a day?

Think about it.  Shouldn't there just be one tide on the side facing the Moon?  Counter to what we expect, there is a high tide on the side of Earth facing the Moon -and- a high tide on the opposite side.  Why is that?  Well, explanations abound and many of them are rife with misconceptions.  It's been said that the high tide on the opposite side of the Moon is caused by centrifugal motion since the moon is large enough and close enough that the center of mass between the two off sets the Earth's rotation (think of a binary star system--they really orbit each other).  Another common explanation is that the moon pulls the Earth away from the water on the opposite side of the Earth, bunching it up together.  

The real explanation, as best I understand, is that almost the entirety of the effect is due to gravity (although, I imagine multiple causes are at play).  The diagram illustrates.  On the side closest to the moon, there are two main gravities pulling--the Earth pulling towards its center of mass, and the moon pulling towards itself.  The net effect is a well of water.  On the top and bottom (and right angle sides) of Earth the two gravity effects are the Earth pulling down and the Moon's gravity pulling the water towards the high tide.  This effect causes low tide.  On the opposite side of Earth from the Moon, the two gravity pulls of Earth and Moon are working in concert to cause the water to slightly bunch up.  Add this effect to the fact that low tides exaggerate the appearance of high tides and we now have two high tides a day.

Bubbles Don't Float

And the since a liquid is denser the deeper it gets, there is slightly more molecular pressure on the bottom of a bubble.  This difference in pressure  pushes the bubble up.
