Space station Definition and 115 Threads

ok this is a rly simple problem I just can't figure it out. There is a rocket traveling from Earth to a space station (which are in the same reference frame). Earth sends light signals at some interval to the rocket, which then sends the signals to the space station. When I work this out I...

A spacecraft (Lo = 80 m) travels past a space station at speed 0.7c. Its radio receiver is on the tip of its nose. The space station sends a radio signal the instant the tail of the spacecraft passes the space station. (a) What is the length of the spacecraft in the reference frame...

Question: A space station shaped like a giant wheel has a radius 109m and a moment of inertia of 5.07x10^8 kgm^2. A crew of 180 is living on the rim, and the station is rotating so that the crew experiences an apparent acceleration of .8g. When 140 people move to the center of the station...

I really don't understand the universal gravitation chapters and the satellites one. It is sooo confusing. So can anyone help me with these questions. 1. Determine the magnitude of the apparent of a 56 kg student standing in an elevator when the elevator is experiencing an acceleration of (a)...

Does anyone have an idea of an innovation i could design to assist astronauts in the contruction of a space station? I really have no ideas, and am looking for something simple but really clever and effective. Help will be extremely appreciated :smile:

Hi, I was hoping I could get some help on these problems. Here's the first problem: 1. A projected space station consists of a circular tube that is set rotating about its center (like a tubular bicycle tire). The circle formed by the tube has a diameter of about D = 1.30km. What must be the...

A proposed space station includes living quarters in a circular ring 50.3 m in diameter. At what angular speed should the ring rotate so the occupants feel 0.411 g where g is the gravitational acceleration on the surface of the Earth?

Junior level Physics problem I am having trouble with: Some plans for a future space station make use of a rotational force to simulate gravity. In order to be effective the centripetal acceleration at the outer rim of the station should equal about 1g, or 98.1 m/s^2. However humans can...

Hi guys.what do you think of the answers i have got for the questions below.If you think i have made any mistakes please do say so.I think my answers are weird, a) A space station orbits the Earth in every 91 mins .calculate the angular speed of the space station ans) 91/60 times 2pie=9.52...

Another problem (oy!): ------A projected space station consists of a circular tube that is set rotating about its center (like a tubular bicycle tire). The circle formed by the tube has a diameter of about D = 1.02km. What must be the rotation speed (in revolutions per day) if an effect equal...

Quick physics help please First off, I'm new to the board and want to say hi to everyone! I hope i can give and take from this site, i should be helpful in the chem forums, but physics is not my best. I have 2 quick questions if you could help me that'd be great. A space station is shaped...

A Little Help?? Hey I'm doing an important physics project for my final grade in physics and I'm having a hard time, can anyone explain to me exactly what physics is involved in the International Space Station?? Any help would be appreciated! Thanks you so much!

Not my opinion, but I am hearing talk, just now again in a review of the Top Science Stories of 2003 on The Science Channel, in which the viability and value of the space station and the shuttle are questioned. The main questions were: 1). What are we accomplishing on the space station...

incase anyone cares. The bump in the night that the crew of the International space station heard was that of a leak, between pods. There will be a "BOOOM!" if you know what I mean. I guess kind of like Apollo 13.

I woke up at 4:30 PST (San Diego) and couldn't go back to sleep so I decided to take my telescope out and finally check out Saturn, the Orion Nebula, and Mars again. They looked awesome through the 8" telescope and I wish I was able to take pictures. Then around 5:30 I saw a really bright object...
