Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:

W = Force x distance

W = 84 J = F (7.0 m)
F = 12 N

Hope this answers the question.

By definition, the work done is given by:

W = Fd

Where,

F: force applied in the direction of displacement

d: distance traveled

Substituting values we have:

84 = F (7)

From here, we clear the value of force.

We have then:

F = \frac{84}{7}

Rewriting we have:

F = 12

Answer:

It takes 12 N of force to pull the wagon.

V125BC [204]
DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
