The Foucault Pendulum show that the Earth rotates because the pendulum would swing so slowly that it would appear to change direction as the Earth moved away. 
<h3>How does the Foucault pendulum work?</h3>
The Foucault pendulum was able to demonstrate experimentally that the Earth revolves around itself with an angular velocity Ω, in a period of 23 hours, 56 minutes and 4 seconds. 
Thus, Foucault knew that the longer the string attached to the weight, the slower the swing of his pendulum. He could attach the string above to an almost frictionless pin, and if he used a very large weight, the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.

Karen is NOT correct. This is because the sun's energy is a renewable resource. This means that its  use is sustainable hence it is a substance of economic value that can be replaced or replenished in the same or less amount of time as it takes to draw the supply down. Though the sun is a finite resource,  it cannot be depleted within human timescale.
