How long does it take a lightbulb to use 1kj of energy?

13.3 seconds

Explanation:

The complete question is...

How long does it take a 75 W lightbulb to use 1 kJ of energy?

The Energy of the bulb E = 1 KJ = 1000 J

The power rating of the lightbulb = 75 W

The power rating of a bulb P = Energy used per unit time = E/t

substituting, we have

75 = 1000/t

t = 1000/75 = 13.3 seconds

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
