I Need Some Help, Please

[NailsII]

Second time round I get 9,840,604,389,142 cm3 which is over 2.5 times to the sun and back.

I'll get me coat.........

3r[sup]2[/sup]y - 3yr[sup]2[/sup] + y[sup]3[/sup] = (3960[sup]3[/sup] – 3955[sup]3[/sup])miles[sup]3[/sup]

The second term should be 3y[sup]2[/sup]r.

Otherwise ... good point.

3y[sup]2[/sup]r is likely to be too small to be significant given that y[sup]2[/sup] is 10[sup]-10[/sup].

Hence, Chalnoth's approximation is probably good ... and, of course, comparing to the above answers ... it is good.

I got the same as Plindboe and Chalnoth

distance from earth is 5,701,973 km, which is around 3,542,864 miles.

Water volume was 4085638331 km[sup]2[/sup] I then multiplied with 100000 to get the area of the 1 cm thick layer of water. This was then used in the sphere surface area calculation giving r[sup]2[/sup], the root of this gave the distance from earth.

Keep in mind, no water sphere would exist there. The low temp and pressure would simply evaporate the water into a cloud of tiny ice crystals that would then drift off as gravity dictated.

Well, technically, if it wasn't affected by any outside force, it would collapse under its own gravity.

There would also be a fair amount of photodissociation taking place due to solar radiation.

You people don't get it... God kept the ice shield together. He just told the physical laws of the unvierse to Take A Hike.

And allegedly hit the moon very hard on all sides as He moved the water away, leaving great big holes that look just like impact craters.

I wonder how the Voyager probes (among others) managed to fly through that layer at 40.000 miles per hour without harm.

You got a problem with that??

Well its not there anymore It collapsed during Da Flood!

Let me get this straight - some super-intelligent being created the universe from nothing, made humans from dust and couldn't avoid the moon when removing a shed load of water from the earth?

Can he not drive?

 

[Hespera]

Of course all of the other solid planets or moons also have lots of impact craters.
Meteors hit the earth every day. That comet hit jupiter, for everyone to see.

Why is there a need for some weird concoction of a story about meteor craters when they are still being made the same way as always.

LOL! God can simply tell driving to TAKE A HIKE!!!11111

For a little lesson in both approximation and using the Google calculator, here:

First, since the Google calculator is going to take care of our units, let's leave those in and just do the following. I'll rewrite the last line in the above train of thought, combining terms on the left, and writing the expression the number on the right came from:

3r[sup]2[/sup]y - 3ry[sup]2[/sup] + y[sup]3[/sup] = (3960[sup]3[/sup] – 3955[sup]3[/sup])miles[sup]3[/sup]

with:
y = 1cm

Now, first of all, we know that the answer to r is going to be pretty big: it's got to be significantly larger than the nearly 4,000 miles we already have, which is vastly larger than the number y (1cm). Since r is going to be something like a million times larger than y, we are only affecting things around the sixth decimal place (or further out) by just dropping all but the term with the greatest power in r. So we can simply rewrite the above as:

3r[sup]2[/sup]y = (3960[sup]3[/sup] – 3955[sup]3[/sup])miles[sup]3[/sup]

Rewrite in terms of r:

r = sqrt((3960[sup]3[/sup] – 3955[sup]3[/sup])miles[sup]3[/sup]/(3*1cm))

Now we can just plug that into the Google calculator to get a result.

Voila!
3 550 016.71 miles

(put whatever units you want for an alternative answer)

r[sup]2[/sup] = 396 x 10[sup]3[/sup] + y[sup]3[/sup] = 3955 x 10[sup]3[/sup] = 3.84171392 x 10[sup]21[/sup]

y[sup]3[/sup] = 3955 x 10[sup]3[/sup] + r[sup]2[/sup] = 396 x 10[sup]3[/sup] = 3.84171392 x 10[sup]21[/sup]

r[sup]2[/sup] + y[sup]3[/sup] = 3.84171392 x 10[sup]21[/sup]

The correct answer = (3 ÷ 1 =) 3 miles.

Relative to the information above, your "Google calculator" (result) answer is 100% incorrect.

Wow. So you're saying that it would have decreased its radius by 3 orders of magnitude?

I'm going to have to call troll here.
