A light source, S, is located 2.0m below the surface of a swimming pool and 1.5m from one edge of the pool. The pool is filled to the top with water.
a) At what angle does the light reaching the edge of the pool leave the water?
b) Does this cause the light viewed from this angle to appear deeper or shallower than it actually is?

Last night I stood outside of my house and watched the moon lierally moving and not moving by the hour but by the second. It moved up and then left and then I checked later and it was in the right side of the sky, being closely followed by Mars...can anyone explain this to me?

I have a refill and I want to know how long I have to wait to get that refill. I am following the directions, but arm leaving town before I think the refill would be due. It is a cough medicine called Tussionex. It is a controlled substance. I have 300 milliliters and am to take 1 teaspoon every 12 hours. Just really wanted to know how many teaspoons were in the 300 milliters. Thanks if anyone can help . I dont want to take more or less than prespribed. I like to follow directions. But wtih the upcoming trip, I fear a frefill would be too soon. Pleas give me any help yo can.

Hawking or Susskind? Not saying that either one of them have it right, at this time but that more info will come over time. But which one seems to have a better handle on it at this time?

*Not invented by me.

First was nothing.
A fold in the void separates fullness of nothing, and absence of fullness.
Which are the same in essence but opposed.
Thus the first pair of poles was made.
Fullness of nothing was on top,
Nothingness of something under.
By that occasion the void splits again.
It is at the same time definite
And not definite.
On one side goes definition and on the other, non definition.
This feeds again the opposition between fullness and nothingness, since we now have 4 parts in the void.
And, this indicates an evolution.
A change.
A flow.
The flow itself is an entity feeding the pole of fullness.
A succession of other folds are drawn in the void,
until the potential at the poles is big enough to shape a wave.
Which is not yet matter.
The wave is an entity and again feed the primal pole of fullness.
Many waves cumulate until they build a charge.
And light is made from that charge.
Again two new entities light and charge feed the poles.

I tried this question on some learned friends with this result: seems logical; if mitochondrial DNA comes from the mother to daughter its ok for the y to come from the dad; can't be the same y due to diversity; what's a chromosome; asking why (Y) is a man thing. Here is a problem. Mitochrondia ALSO enter the egg as part of the sperm cell .No real problem, unless you are hung-up on mother to daughter transfer of M-DNA. Because which ever human sperm fertilized the first human egg the M-DNA was forever mixed.Yes, to the female offspring but ALSO to a male kid. Each of which continued to pass on M-DNA to a fertilized egg/zygote. It should be noted that " M" of the M-DNA is not "maternal" but "M"itochondrial.And IT didn't come from a MOTHER somewhere in Africa umpteen years ago. You could just as well trace the paternal mutation rate in subsequent generations since the sperm number of M-DNA is tiny compared to the egg .What say ye? Please a reference, if you know of any.

Moon On April 11th 1979, longitude 86oW 12h58pm

1 angle from greenwich at 0h
april 11th, midnight 02LI41
april 12th, midnight 15LI05

A - Get the difference between these two days
(15-2)o + (5-41)'' = 13o - 36''
= 12o24
= 12o + 24'' *1o/60''
= 12.4o

B - Get the offset at 12h58
12h58 = 12h + 58min * 1h/60min
= 12.96h
12.96h * 12.4o / 24h = 6.696o --> difference added to value at midnight
War time not in effect.

C - Add the offset to basic value of the day
Libra's spawn is between 270o and 300o
And starts at 270o
2Li41 = 270o + 2o41
= 272o41
272o + 41'' * 1o/60'' = 272.683o
+ 6.696
= 279.379o

2. adjustment for longitude
+86o --> earth spins from east to west
would be -86o if the longitude was 86o East
= 365.379o

3 adjustment of moon's position during that offset of time
365.379o * 1 lunar cycle / 27.32 terrestral cycles = 13,374048316251830161054172767204o
365.379o + 13.374o = 378.753o

4. Delay of light from moon to earth
1.2 seconds approx.
1.2s * 1h/3600s = 0.0002777....h
0.00027h * 15o/h on earth = 0.004166...o
378.753o + 0.004o = 378.757o
Nearly negligible

5 angle translated to sign
378.753o > 360o
Therefore the cycle is completed once
378.757o - 1cycle * 360o/cycle = 18.757o

6 Spawn of capricorn 0o to 30o

Hence 18.753o means 18.757o capricorn
Or
18o + 0.757'' * 1o/60'' = 18o45 capricorn

The Moon hits earth with a 18CP45 angle type
at longitude 86o, 12h58pm

I need a bit of help with solving a hydronium ion concentration problem.
I need to find the ion concentration of a solution that's 1.5 molar acetic acid and .20 molar sodium acetate.

If possible, could you explain how you got this answer so I can understand a bit better about how you came to this conclusion. Thanks.
