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 6000 Joules. Therefore, choice D is correct.

Answer:

<h2>Solution :-</h2>

We know that

Work = Force × Displacement

Work = 500 × 12

Work = 6000 J

Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton

pishuonlain [190]

Hello!

Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.

Data:

Hooke represented mathematically his theory with the equation:

F = K * Δx

On what:

F (elastic force) = 2 N

K (elastic constant) = 4 N/cm

Δx (deformation or elongation of the elastic medium or distance from a spring) = ?

Solving:

$F = K * \Delta{x}$

$2\:N = 4\:N/cm*\Delta{x}$

$4\:N/cm*\Delta{x} = 2\:N$

$\Delta{x} = \dfrac{2\:\diagup\!\!\!\!\!N}{4\:\diagup\!\!\!\!\!N/cm}$

simplify by 2

$\Delta{x} = \dfrac{2}{4}\frac{\div2}{\div2}$

$\boxed{\boxed{\Delta{x} = \dfrac{1}{2}\:cm}}\Longleftarrow(distance)\end{array}}\qquad\checkmark$

Answer:

B.) 1/2 cm
