circular

...kilometres must it travel? A satellite is in a circular orbit 225 km above the equator of the earth. How many kilometres must it travel for its longitude to change by 78.2°? Assume the radius of the earth equals 6400 kilometres.

I've seen pictures of circular-shaped boats on google image search, but where can I buy one? I'm talking about something like this: http://pro.corbis.com/images/VV1185.jpg?size=67&uid=%7B4FF612DF-2077-4D4B-B606-D3948D5D44E8%7D Or this...

I always see this circular device on one of the windows on the bridge of a large ship. It is about two feet in diameter. Its always there, on old ships and new. WHAT IS IT?

Is this answer correct or wrong? thanks you 5. While a car travels around a circular track at constant speed its A) acceleration is zero. B) velocity is zero. C) both of these. D) neither of these. <-- Answer

Why there is no mechanism for altering the trajectory? I think it would need a huge force to launch a satellite into circular orbit using a cannon buut why?

Determine? A satellite moves in a circular orbit around the Earth at a speed of 5034 m/s. Determine (a) the satellite's altitude above the surface of the Earth and (b) the period of the satellite's orbit.

(a) Find the time of one revolution. (b) Find the radial acceleration of the satellite in its orbit.

...Earth at a height of 3600 km? Mass of Earth: 5.98 E 24 kg Equatorial Radius of the Earth: 6.378 E 3 I'm not sure if these are needed for this problem but I provided them just in case. This was everything that was given. I'm not sure this problem is even possible..
