Determine the sampling rate for an analog telephone signal transmitted across a single channel of a T1 line with a data rate of 128 Kbps (kilobits per second), assuming that a single sample is converted to an 8-bit integer.

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)

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
