What amount of work is done when a force of 50 n is used to drag an object a distance of 20 meters across a floor?

Work done, W = 1000 J

Step-by-step explanation:

It is given that,

Force acting to frag an object, F = 50 N

It covers a distance of 20 meters, d = 20 m

Work done is given by the product of force and distance travelled by the object. Mathematically, it is given by :

W = 1000 J

So, the work done when the object is dragged is 1000 J. Hence, this is the required solution.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
