Answer:

\boxed {\boxed {\sf 6000 \ Joules}}

Explanation:

Work is the product of force and distance.

W=F*d

The force is 500 Newtons and the couch is raised 12 meters above the ground.

Substitute these values into the formula.

W=500 \ N * 12 \ m

Multiply.

W=6000 \ N*m

  • 1 Newton meter is equal to 1 Joule.
  • So, our answer of 6000 N*m equals 6000 J

W= 6000 \ J

The work done to move a 500 Newton couch 12 meters is <u>6000 Joules</u>. Therefore, choice D is correct.

Answer:

<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>

We know that

Work = Force × Displacement

Work = 500 × 12

Work = 6000 J

Are the units of the formula ma = mv2/2 dimensionally consistent? Select the single best answer.
Vesnalui [34]

To solve the problem we will simply perform equivalence between both expressions. We will proceed to place your units and develop your internal operations in case there is any. From there we will compare and look at its consistency

ma = \text{Mass}\times \text{Acceleration}

ma = kg \cdot \frac{m}{s^2}

At the same time we have that

\frac{1}{2}mv^2 = \text{Mass}\times \text{Velocity}^2

\frac{1}{2}mv^2 = kg ( \frac{m}{s})^2

\frac{1}{2}mv^2 = kg \cdot \frac{m^2}{s^2}

Therefore there is not have same units and both are not consistent and the correct answer is B.
