There are 2 Flip_Flop with logic between them. Given Clock
to Q delay, logic prop. delay, set up and hold times specify
maximum clock frequency of system.
What happens if second output fed back to first input. Any
changes? What happens with timing if second output is fed
back to logic between the flops? Good Luck!

This is related setup and hold time violations. Answer is:

Tc-q + Tsetup + Tcskew + Tcomb <= T period (setup)

Tc-q + Tcomb - Tcskew >= Thold (holdtime)

Short path -> possible hold time violation.
Long path -> possible set up time violation.

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
