It can rn a battery, drug companies & the US Center for Disease & Prevention all buy pee. They are also seperating the phosphate & nitrogen by 50% to purify the urine enough to drink. Know of any other uses? Why is urine salty?

How many of these batteries http://www.trojan-battery.com/Products/ProductSpec.aspx?Name=J185H would it take to run this electric motor http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270010898261 for four hours?

I'm trying to determine if the electric motor could fit in a pick up truck and fill the truck bed with batteries.

This is for a statistics project. We're comparing individual players' statistics on the Giants, Mets, Yankees, A's, Marlins, and Dodgers for the 2005 season. Specifically, how their salary correlates with two primary statistics (Batting Average and # of Wins). Where can we find the MEAN and Standard Deviation of these statistics within the major league for the 2005 season so we can calculate P-values and Z-scores/T-scores?

And if evolution is still going on why are no Monkeys evolving? Or any other animal in this case... And now that humans have it so easy what do you think they will be their next form of evolution. I mean we drive in cars. Humans were meant to be runners... How do you think this will effect our next evolution stage....

Why does touching a past version of yourself cause a paradox?
In sci-fi shows which involve the main characters travelling back into their own pasts, protagonists are often warned that touching their past selves will cause a paradox (for example, in the Doctor Who episode 'Father's Day'). If you accept that being part of your own timeline is possible without causing a paradox, why does the act of two versions of yourself from two different times touching cause one?

This is not my question someone asked this in the philosophy section but i want to know the oppinions for those in the physics section.

I'm in my last year of college at the University of Wisconsin. I'm a Zoology and Biological Aspects of Conservation Major. I currently volunteer at a zoo. I'm wondering if anyone knows some good animal care internships, preferably paid internships, or if not, then internships that provide housing.

Speed is measured relative to a stationary object. Velocity is determined by calculating the time it takes to travel a known distance from a stationary object. A cars speedometer measures speed relative to the stationary ground it is traveling on. An airplane measures speed by the same thing, by how long it takes to travel between points of a known distance on the ground.

So when it is said that a spacecraft is hurtling at 46,000 miles per hour beyond the orbit of Pluto towards the next star, what is that speed being compared against? In that part of space, there is no stationary object to calculate velocity. Is it still being compared to a stationary object on the surface of the Earth? At that distance, the Earth is traveling through space in orbit around the sun, which is traveling in orbit around the galaxy, which is traveling through space around who knows what.

So, what is the spacecraft traveling at 46,000 miles per hour from or towards that can be measured?

At a certain moment, an asteroid has this position in heliocentric ecliptic coordinates. (Distances are in astronomical units.)

x= +0.5877971
y= -2.098983
z= -0.008080998

You are able to determine the inclination and longitude of ascending node for the orbit.

i = 0.003996730 radians
L= 6.170532 radians

You know the true anomaly for that point in the orbit.

Q= 3.14159265 radians

What is the argument of the perihelion for the orbit?
