To determine which option is causing the wheel to turn in the diagram modeling a device that is foundational for the modern electrical turbine, we need to consider the typical energy sources that power such devices.
-
Option A: Force from the mechanical energy generated by the solar radiation causes the wheel to turn.
- Solar radiation typically converts to thermal energy or can be converted to electrical energy through solar panels, not directly mechanical energy.
-
Option B: Force from the mechanical energy generated by the moving water causes the wheel to turn.
- This is a plausible answer. In many hydraulic turbines and water wheels, moving water causes mechanical energy to be harnessed and turns the wheel.
-
Option C: Force from the thermal energy generated by the solar radiation causes the wheel to turn.
- While thermal energy can create motion (like in a steam engine), this is less common for the type of devices associated with modern turbines at a foundational level.
Given the context of a device foundational to modern turbines, option B is the most appropriate answer. The turning wheel is caused by the force from the mechanical energy generated by the moving water.
