please till me about at lest one people who is not straight that have lived to be at lest 50 years old or longer is better. are any of u in good heath? can some one till me about a homsexual(female or male homsexual) relationship that they had lasting at lest 5 years? can some one till me of a relationship that they had with the same sex that lasted for 5 or 8 years and was fathful and wasnt cheated on?
I asked theses questions because of what i read at the web site witch is giving below.



here s the web site www.familyresearchchinst.org.

go to this site and u will see where it talks about them only living to be in late 40s and u will see a lot of other info that caused me to ask the questions that i asked.

the inputs of the system are inertial movements of an object (car). it outputs acceleration (from accelerometers) and attitude (yaw, pitch, roll - from gyroscopes). it is then processed and analyzed to compute for the movements the object had done. With an initial coordinate(starting location), the data may be used to find for the corresponding coordinates of the final position.(longitude, latitude, etc)... is my understanding correct?

I've been to Boracay, Philippines, and it's breathtaking especially its powdery sand. There is nothing like it anywhere in the world. But there's one thing I noticed tho when I went bathing and these were the presence of floating algae along its shore. To my knowledge, algae thrive where there are plenty of nutrients to sustain its growth. So, does this nutrients being provided by the numerous establishments and residences situated nearby along the shore by way of their sewerage system? I understand the island has no sophisticated and huge sewer plant large enough to service all the commercial business establishments and residences mushrooming at the Boracay island.

I mean you would think that we would know more about our planet because we are already here on it so they should stop going crazy about the space thing. We do not know if there are aliens out there, but we do know that there is a bottom of the ocean and that there is life down there. They should not worrie with one thing until the other is solved. The jump to space is huge compared to the plunge to the bottom of the ocean.

A uniform disk (like a record turntable) turns with a frequency of 4.8 rev/s around a frictionless spindle. A non-rotating rod of the same mass as the disk and length equal to the disk's diameter is placed on the freely spinning disk so both turn around the spindle.

a) First consider the idealized case where the rod sticks tightly to the disk immediately upon impact. How fast does the combination turn?

b) More realistically, there is a frictional force between the two surfaces such that the magnitude of the torque slowing down the disk is equal to the magnitude of the torque speeding up the rod (this is a consequence of Newton's 3rd Law.). Hence we have alpha*disk = -C alpha*rod, where alpha generically means angular acceleration. Find the constant C.

c) The disk slows and the rod speeds up until they are moving together. Find the frequency with which the combination turns in this case.

d) Suppose Idisk = .65 kg m2. What is the magnitude of the kinetic energy lost due to friction?

This is for a little project I've been thinking about for a while and I think I know the answer, I'm just not sure.

If you have two little tiny screens about an inch or so in front of your eyes (think virtual boy for those who remember it), you can make the image appear 3D if the angles on each image are slightly different and then you project them over each other.

What do you do if you can't change the angle each image is displayed at. When they're projected over each other the angle of sight for each image is the same so it appears 2D.

Would angling the screens, rather than the images on the screens, work to correct this, and if so would the quality suffer? How could I correct any blur or at least make it better?

If you have any other suggestions please let me know. The only requirements are that any extra devices be very small and that minimum blur is achieved.
