The semiconductor chip at the heart of a personal computer is a square 5mmon a side and contains 10^10electronic components.(a)What is the size of each component,assuming they are square?(b)If a calculation requires that electrical impulses traverse10^4components on the chip,each a million times,how many such calculations can the computer perform each second?(Hint:The maximum speed of an electrical impulse is about two-thirds the speed of light.)

Explain in detail DC and AC current.

Ion Suppose we have an Allen-Bradley SLC 500 PLC connected to two process switches as shown in this illustration: 120 VAC power Power supply L2/N Gnd Slot 0 Slot 1 Slot 2 Slot 3 (processor) (discrete input) (discrete input) (discrete output) Processor Input 00 2 feet 37 PSI T 0123 0000 0000 4587 INO IN1 IN2 IN3 IN4 IN5 IN6 IN7 Ø COM COM Input 0123 0000 INO IN1 IN2 +N3 IN4 INS ING IN7 COM COM 0000 FOOT Output OFN3 0000 0000 VAC 10 OUTO OUT1 OUT2 OUT3 VAC 2 OUT4 OUT5 OUT6 OUT7 Determine the bit statuses of I:1/3 and I:1/5 when the level switch senses 3 feet and the pressure switch senses 14 PSI.

Fill in the blanks: Given the model for position control system, find the value for K1 and K2 so that the peak time is equal to 0.5 s and the %OS is equal to 3%. K1= 93.2070 K2= 0.129 I 446 23
