You and a friend are spending the weekend making up missed lab experiments. you are on to second - semester material and are studying the electrostatic interaction of two charges. you notice that two charges are exerting a certain force on one another. if the distance between two electric charges doubles, then the force they exert on each other changes by how much?
2 times as large
4 times as large
1/4 as large
1/2 as large

1/4 as large  

Explanation:

Lets take

q₁ and q₂ are the charge on the particle and d is the distance between them.

We know that electrostatics between two particle given as

When distance become double d'= 2 d

So new force F'

It means that force will become one forth of initial force.

So answer is 1/4 as large .

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

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
