When moving a couch you exert a force of 400 n and push it 4.0 how much wokr have you done on the couch

W = 1600 J

Explanation:

Given in the question,

force exerted = 400N

distance it covered = 4m

The general formula for work and for determining the amount of work that is done on an object is:

W = F × D × cos(Θ)

The SI unit for work is the joule (J)

Plug values in the formula

W = 400(4) cos(0)

W = 400(4)(1)

W = 1600 J

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.
