Assume that constructing a DFA from DFA(s) takes polynomial time. Also assume that TM T can decide ETM in polynomial time. Provide an analysis of the time complexity to show that TM F below that decides EQTM runs in polynomial time. F = On input (A, B), where A and B are DFAs:
1. Construct DFA C such that L(C) = (L(A) n L(B) U (L(A) N L(B)).
2. Run TM T that decides EDFA from Theorem 4.4 on input (C).
3. If T accepts, accept. If T rejects, reject.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.

Analyze the factors that influence the choice between the following pairs of processes to make the products indicated: i) sand casting versus die casting of an electric-motor housing ii) thread rolling versus machining of a bolt for high-strength application. (co3/c5)
