After World War 2, The United States and Russia engaged in an unfriendly relationship. Each side wanted to better than the other in anything, which included space... Wednesday, 7th Dec 2011 - 8:12 pm A spacecraft of mass 1,000 kilograms is in an elliptical orbit about the Earth, as shown above. At point A the spacecraft is at a distance rA = 1.2 x 107 meters from the center of the Earth and its velocity, of magnitude VA = 7.1 x 103 meters per sec... Wednesday, 7th Dec 2011 - 5:12 pm On Dec. 1, a camera onboard NASA's STEREO spacecraft recorded a wave of electrically charged material shooting out from the sun and blasting Mercury. Footage of this "coronal mass ejection" (CME), as such events are called, has caught the attent... Wednesday, 7th Dec 2011 - 3:12 pm Some satellite imagery is automatically added - can I add too? I noticed they come out much sharper and detailed when applied to the surface.
I'd like to see this particulars one:

http://en.wikipedia.org/wiki/China_... Wednesday, 7th Dec 2011 - 3:12 pm I was just thinking about how massive objects distort spacetime and create "depressions" in it that makes near matter pulled towards the center, and the technicalities of this. Then I was thinking about how supposed aliens could hide in gravitational... Wednesday, 7th Dec 2011 - 2:12 pm My friend has this math question:
One source of space debris is nonfunctional spacecraft. At the end of 1993, scientists tracked 1550 nonfunctional components in orbit and projected 42 such objects are added each year. Suppose that an average of 15 ... Wednesday, 7th Dec 2011 - 12:12 pm A spacecraft containing air at STP is struck by a micrometeor that makes a hole 5 mm in diameter. Calculate the initial rate at which air escapes through the hole, in number of air molecules leaving the spacecraft per second. In the previous chapter ... Tuesday, 6th Dec 2011 - 9:12 pm Okay, so I'm making these questions about Special Relativity and I got a few questions.
I'll start off very basical:
"At what speed will the relativistic and Newtonian expressions for kinetic energy differ by 10%?"
I figured this wou... |
