If computer A is 3.5 times as fast as computer B; and computer B is 1.5 times as fast as computer C. Find the execution time needed for computer A to complete a program which takes 10.4 millisecond by computer C. Show your steps in details.

Different objects are moving on a conveyor belt. Let’s say, circular balls, square blocks and rectangular blocks. All three types of objects are collected in the same sized box. As these types are different in size and shapes as well, number of objects to be placed are different for each type. Set counter value according to different sized objects’ detection. Implement automation of this in PLC using Ladder Diagram programming language.

What is the purpose of the break statement? Force the termination of a program. When a break statement is encountered in a loop, the loop terminates immediately and the execution resumes the next statement following the loop. To produce the systematic code, and the break statement does not affecting the program. To make the code easy to understand.

a) In Assembly programming what is the functionality of the following instructions DECFSZ ВTESC MOVLW MOVWF goto b) A piece of code is required for a time critical activity. Should this be written in assembly language or C? Explain your answer. 5 Explain the difference between the (For) and (While) loops. Highlight the main components of the (For) loop that are required for its execution. Consider the following C program designed to run on a PIC 18F4455. int main(void) 2 { 1 double voltage; double current; double milliwatts; double energyUsed; double cummulativeEnergy = 0; while (1) { voltage=analogRead (VOLTAGE_PIN)*voltageScaleFactor; current=analogRead (CURRENT_PIN)*currentScaleFactor; milliwatts=voltage*current; energyUsed=milliWatts*0.5; cummulativeEnergy=cummulativeEnergy+energyUsed; 10 11 12 13 14 15 _delay_ms (500); 16 } 17 a) What is the role of the symbols "{" and "}" b) The code here is indented. Explain the importance of indentation N m 4 n Or 00 o A m
