A cricket ball swings due to the asymmetrical airflow around it caused by the seam position and surface roughness.

• Swing is caused by the ball creating turbulent airflow around it due to its seam position and surface roughness.

• The rough side of the ball creates more drag, causing it to swing towards that side.

• The Magnus effect also plays a role in swing, where the ball's spin creates a pressure difference leading to movement in the air.

• Fluid mechanics principles such as Bernou...read more

The Carnot cycle is a theoretical thermodynamic cycle that operates between two heat reservoirs.

• Consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, adiabatic compression

• Efficiency of Carnot cycle is determined by the temperatures of the two reservoirs

• It is the most efficient heat engine cycle possible

AC is a device that cools and dehumidifies air in a room, while a refrigerator is a device that cools and preserves food.

• AC is used to cool and dehumidify air in a room, while a refrigerator is used to cool and preserve food.

• AC typically has a larger cooling capacity compared to a refrigerator.

• AC uses a refrigeration cycle to cool the air, while a refrigerator uses the same cycle to cool its interior.

• AC units are usually larger in size and have more powerful compressors than ...read more
