How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?

ElenaW [278]

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

<u>Work done ( in joule, J) = 21 J (in joule)</u>

A garden has a circular border and a fountain in the center. I measured the distance from one side of the garden to the other, g

Snezhnost [94]

Answer:

The length of the border is approximately 4 feet.

Step-by-step explanation:

Since the garden has a circular border we can apply the formula for the circle's length, which is shown below:

$length = 2*\pi*radius$

Where the radius is half the diameter. The diameter is the distance between two points in the circle going through the center, therefore for this garden the diameter is 1.2 feet and the radius is 0.6 feet. Applying this to the formula gives us:

$length = 2*\pi*0.6\\length = 1.2*\pi\\length = 3.8$

The length of the border is approximately 4 feet.
