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.

A large software development company employs 100 computer programmers. Of them, 45 areproficient in Java, 30 in C, 20 in Python,
melisa1 [442]

Answer:

18, 13, 19

Explanation:

Number of computer programmers proficient only in Java = 45 - ( 1+1+6) = 37

Number of computer programmers proficient only in C++ = 30 - (6+1+5) = 18

Number of computer programmers proficient only in python = 20 - ( 1+1+5) = 13

Number of computer programmers are not proficient in any of these three languages = 100 - ( 37 + 18 + 13 + 1+ 1+ 5+ 6 ) = 100 - 81 = 19

RADIAC instruments that operate on the ionization principle are broken down into three main categories based on what?
mash [69]

Answer:

Electrical potential.

Explanation:

RADIAC Meter or instruments ( also known as radiation monitoring instruments) are measuring instruments that uses the principles of gaseous ionisation to conduct electricity flow internally to deflect the pointer for its Meter readings. These instruments can be analogue or digital.

They are used in industries to monitor the operation of certain equipments and processes. The level of electrical potential flow in the system determines the state or category of the instrument. Out of six, there are three main categories of electrical potential level.

luda_lava [24]

Answer:

B. Fuser unit

Explanation:

Based on the scenario that is being described it can be said that the most likely problem is the Fuser unit. This is a part that plays an important role in the printing process. This unit melts the toner and compresses it in order to leave the impression on the paper with heat. A faulty fuser unit will not compress correctly and leave wet ink on the paper causing it to smear.
