5.(Optional with 10 bonus points) Design a 64-bit adder with a module name of add64, which takes in 64-bits input X, Y to generate the 64-bit sum S, and carry-out bit C. To generalize the design for n-bit adder, we may use parameter as follows parameter n=64; // 64 bit adder input [n-1:0] X, Y;// use of parameter n (a) Briefly describe your algorithm / pseudo codes (b) Write your Verilog design

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

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.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false
