A 10 cm wide box is held between two springs in a 1 m gap on a frictionless surface. The left spring has a natural length of 80 cm and spring constant of 200 N/m. The right spring has a natural length of 90 cm and spring constant of 350 N/m. How far is the center of the box from the left edge in m

The distance is  

Explanation:

From the question we are told that

     The width of the box is

     The gap is of length

    The natural length of the first spring is

     The spring constant of the first spring is  

     The second spring has a natural length of

      The spring constant of the first spring is  

Let the distance from the center of the box to the left edge be x

      So at equilibrium

The force applied by the first spring is

and

The force applied by the second spring is

Now at equilibrium

So

    substituting values

        =>  

        =>  

          =>  

change tension

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
