1.Explain reversible and Irreversible Processes. Describe the working of a Carnot engine. Obtain the expression for efficiency. |
|
Answer» I hope it will help youExplanation:Reversible process:− a reversible process is a process WHOSE direction can be 'reversed' by including infinitesimal CHANGES to some property of the system via its SURROUNDINGS. Irreversible process:− In a science a process that is not reversible is called irreversible. this concept arises frequently in thermodynamics. working of carnot engine:− According to the carnot theorem, the irreversible engine will always have a greater efficiency than the irreversible one. The reversible heat engine operates on a reverse cycleand functions as a heat PUMP (or refrigerator). The carnot CYCLE irreversible representing the upper limit on the efficiency of an engine cycle. |

Newton's 3 Law of Motion with example |
|
Answer» Explanation:Newton's third law states that when two BODIES interact, they apply forces to ONE another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. ... For example, a book RESTING on a table applies a DOWNWARD force equal to its weight on the table. |

17. (a) What is dispersion of light? (b) Explain how rainbows are formed?(c) In the formation of white light by a prism, which colour is deviated least andwhich colour is deviated most? |
|
Answer» A)In optics, dispersion is the phenomenon in which the phase velocity of a wave DEPENDS on its frequency. Media having this common property may be termed DISPERSIVE media. Sometimes the term chromatic dispersion is used for specificity.B)A rainbow is caused by SUNLIGHT and atmospheric conditions. Light enters a water droplet, slowing down and bending as it GOES from air to denser water. The light reflects off the inside of the droplet, separating into its COMPONENT wavelengths--or colors. When light exits the droplet, it makes a rainbowC)The bending of red component of white light is least while most for the violet component.follow me and mark me as brainliest |
