Which energy sources(input) can cause the turbine(wooden wheel) to spin and generate electrical energy

Your town is considering building a biodiesel power plant describe at least two advantages and two disadvantages

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
