Answer: 9 m

Explanation:

Work is said to be done when an unbalanced force causes displacement of the body.

Force is the product of mass (m) and acceleration (a).

Work = Force × Displacement

⇒W = F.s = ma.s

It is given that mass of the dresser is, m = 250 kg

work done, W = 126 J

Force acting on the dresser, F = 14 N

we need to find displacement, s

⇒126 J = 14 N × s

⇒ s = 126 J/ 14 N = 9 m

Hence, Laurie is able to move the dresser to about 9 m.

<u>Answer:</u>

9 m

<u>Explanation:</u>

When an object moves or displaces along the direction of the applied force application of force, it is said that work is done.

We know the formula of work:

<em>Work = force x displacement </em>

where force = mass x acceleration

So this formula can be further broken down to :

Work = mass x acceleration x d

Putting in the given values to get:

126 = 14 x d

d = 126/14

d = 9 m

Therefore, the dresser was moved by 9m.

If two variables have a non-related relationship and one of the variables is changed, how will the other variable change?
PolarNik [594]

If one of the variables is changed, that tells nothing about what happens to the other one, or IF anything happens, or when, or how long it lasts. Because they are UN-RELATED. You just said so yourself.

None of the choices says this.
