Answer:

A) 20J

Explanation:

Work = Force x Distance

Force = 50N

Distance = 0.4M

Work = 50 x 0.4 = 20J

svlad2 [7]
To find work, you use the equation: W = Force X Distance X Cos (0 degrees)
Following the Law of Conservation of Energy, energy cannot be destroyed nor created.

So you would do 75 N x 10m x Cos (0 degrees)= 750 J

Answer:

Planting of trees on sloped surfaces is a method of conservation that utilizes the roots of plants. Planting trees on such areas would prevent hazards and maintain the soil formation future since the roots would hold the soil together preventing or minimizing any soil erosion.

Answer:

Los 0.0416km

esto se debe a que transponemos la fórmula acelerada y obtenemos Distancia = velocidad × tiempo

también recuerda transponer los segundos a horas viendo que la velocidad es por hora

También tenga en cuenta que no hablo español, así que esto fue extremadamente difícil

If you were trying to describe the difference between power and work you could say...?
Paha777 [63]

Answer:

Look to the explanation

Explanation:

<u><em>Work done</em></u> is  is the energy transferred to or from an object by means

of a force acting on the object.

Work is positive if energy transferred to the object, and  work is

negative if energy transferred from the object.

<em>Work = Force in the direction motion of object × its displacement</em>

W=F*s

The SI unit of the work is joule (J)

<u><em>Power</em></u> is the rate of work

<em>Power = work done ÷ time taken</em>

Power = \frac{F*s}{t}

Displacement (s) ÷ time (t) = velocity (v)

<em>Power = Force × velocity</em>

P=F*v

The SI unit of the power is watt (w)
