What is a non-renewable energy source and will it replenish itself?

A non-renewable energy source is a type of energy that is derived from finite resources that cannot be replenished on a human timescale, such as fossil fuels (coal, oil, and natural gas) and nuclear fuels (uranium). Once these resources are extracted and consumed, they do not naturally regenerate, leading to depletion. As a result, reliance on non-renewable energy sources poses sustainability challenges and contributes to environmental issues like climate change. Transitioning to renewable energy sources, such as solar and wind, is essential for long-term energy security and environmental health.

What is the relation between the angle and the separation point in the flow visualization experiment?

In flow visualization experiments, the angle of the object influences the separation point, which is where the flow detaches from the surface. A larger angle typically increases the pressure gradient and can lead to earlier flow separation, resulting in increased drag. Conversely, a smaller angle can maintain attached flow for a longer distance, reducing drag and improving aerodynamic efficiency. Thus, the angle directly affects the separation behavior and overall flow characteristics around the object.
