Eve is trying to break an RSA message which she knows is based on the modulus N = 282943 Suppose she discovers that p(N) = 281880. Help her recover the primes p and q such that N = pq. Justify your answer. Show all the intermediate computational steps. No exhaustive search argument or direct factoring (either by hand or by some piece of software) will be accepted. Plz, answer as soon as possible.

Thank you

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
