Answer:

PLCs (Programmable logic controller) were original designed as replacement for relay control panels.  Relay is another word for a switch. Relay control panels were made for the control of electronic instrumentents or devices. Later on PLCs were made to replace these timers and relay control panels. PLCs are more reliable, flexible and can work better in the harsh environmental situations then the relay control panels.

Anton [14]

This is all you need to do for this one add quotes around the number to make it a string. Then for the question I don't know if you need to answer it but I said that when there is only one string it creates and addition problem of 24 + 24 and then when there are two strings it puts them right next to each other making it look like the number 2424.

A remediation liaison makes sure all personnel are aware of and comply with an organization's policies.
Ratling [72]

Answer:

False.

Explanation:

I believe this should be the work of a compliance liaison. Assume you have opened up an organization that is growing each day. You have employees who are required to be compliant with all the security standards and policies. Hiring a compliance liaison will ensure that these compliances are being carried out. Each department in an organization should work with a compliance liaison to ensure that its employees understand and comply fully with all security policies.

Light travels at 3 × 108 meters per second. A light-year is the distance a light beam travels in one year.Write a PYTHON program
Art [367]

Answer: This is a python code

def lightyear():

   rate=3*100000000   //speed of light

   seconds=365*24*60*60   //number of seconds in 1 year

   return str((rate*seconds)/1000)+" km"    //distance=speed x time

print(lightyear()) //will print value of light hear in kilometers

OUTPUT :

9460800000000.0 km

Explanation:

In the above code, there is a variable rate, which stores the speed of light, i.e. distance traveled by light in 1 second which is in meters. Another variable is seconds, which store the number of seconds in 1 year, which is no of days in 1 year multiplied by the number of hours in a day multiplied by the number of minutes in an hour multiplied by the number of seconds in a minute. Finally, distance is speed multiplied by time, so distance is printed in kilometers and to convert distance in kilometers it is divided by 1000.

Assume the availability of class named IMath that provides a static method, toThePowerOf which accepts two int arguments and ret
geniusboy [140]

Answer:

cubeVolume = IMath.toThePowerOf(cubeSide, 3);

Explanation:

Following is the explanation for above statement:

Left side:

cubeVolume is a variable with data-type int, it will store the integer value that is the output from right side.

Right side:

  • IMath is the class name.
  • toThePowerOf is the built-in function that takes two arguments of data type int. First is the base and second is the power(exponent) separated by comma. In place of first argument that is the base variable we will pass the variable cubeSide that has been declared and initialize.
  • Now the output will be stored in the variable cubeVolume.

i hope it will help you!
