Response Details:
none of these.  radians are denoted radians but are really unitless, for example, angular frequency has units of radians per second...but they are usually denoted s-1 or 1/s because the radian isn't really a unit.
Don't just read this response and expect to understand everything.  Grab a pen and paper and work it out as you go along, it'll make your life much easier.

I have looked at your posts of  6/2/2008. All are answeres. Nearly ok for all excepot this one. So I am responding to this.
 
Radian itself is a unit. It is the SI unit of angle. 180 degrees = π radian.
1 radian = 57.31 degrees.
In the above MCQ, "None of these" is the correct answer.
