Suppose a speck of dust in an electrostatic precipitator has 1.×10^12 protons in it and has a net charge of –5.00 nc (a very large charge for a small speck). how many electrons does it have?

Explanation:

The net charge is given by the sum of the charges of the protons and of the electrons:

where we have

is the net charge

is the number of protons

is the charge of one proton

is the number of electrons

is the charge of one electron

Solving the equation for , we find the number of electrons:

c) up

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
