Homework Statement



Electrical pulses travel at about half of light speed through coax cables. Determine the pulse delay time for a cable with a length of 20 feet.



Homework Equations





The Attempt at a Solution



I don't think this question is very hard, but I can't find any relevant information in my notes, and our book is just a lab manual. Thanks in advance.

Well speed=distance/time. I could use the speed and distance to find the time. Is that all "pulse delay time" refers to?
 
Yes, that is all there is to it. :smile:

BTW, I have found that electric signals travel about 2/3 c along standard BNC coax cables. But of course, you should use the speed given in the problem statement.
