Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:

If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:

⇒ t = 8.7*10⁻⁴ sec.
Digital vs Analog Audio is completely personal preference and there is no clear winner on which is better.
But there are some pros and cons about both, Analog sometimes distorts when playing and can be easily scratched and ruins the grooves. Analog is believed to be the true representation of the sound when it was recorded. Digital is not the actual recording of the sound, it's actually a combination of binary code. It is also sometimes mixed or remastered in Digital and sounds a bit different to make it sound better. It also depends on the system you are listening it from. You could have a horrible Digital system its playing through and an amazing Analog system playing, of course the Analog system will sound better in that case. Some believe that Digital is on par to overtake Analog in the "true picture of sound" category but some also say Analog will forever be the best at playing sound and Digital will always be the alternative.
But, in the end it's all personal preference and the pros and cons don't overweigh to make one better than the other.
1)How many memory cards (how many can you computer hold)
2)Company (some companies run better than others)
3)Amount of memory (xGb)
Remedial maintenance (corrective maintenance) Maintenance that is performed after a fault, in hardware or software, has been found, in order to correct that fault.
