A resistor of resistance R=9 and a resistor with variable resistance is connected to an ideal battery whose emf is =129V as shown in the figure below. The variable resistor is made up of a rectangular prism of a=7.7cm, b=2.81cm, L=50cm , and the material has resistivity =0.51 . The distance of the contact point from the edge can be adjusted to change the value of the resistance. For x=8.6cm find is the power dissipated on the resistor R. Express your final result with zero decimal places.
