A CRC is constructed to generate a 4-bit FCS for a 9-bit message. The generator polynomial is X4 X3 1. a) Draw the shift-register circuit that would perform this task. b) Encode the data bit sequence 111011001 using the generator polynomial and give the codeword T(X). c) Now assume that the 7th bit (counting from the left side) in the codeword is in error and show that the detection algorithm detects the error

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)
