The force exerted by a rubber band is given approximately by F=F0[L0−xL0−L20(L0+x)2]F=F0[L0−xL0− L02(L0+x)2] where L0L0 is the unstretched length, xx is the stretch, and F0F0 is a constant. Find the work needed tostretch the rubber band the distance, x.

Explanation:

We are given that

Force exerted by a rubber band is given approximately by

Where =Unstretched  length

x=Stretch length

=Constant

We have to find the work needed to stretch the rubber band the distance x.

Work done=

answer; equivalent to a one(1) horsepower motor;

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
