State carnot's theorem and prove it from the kelvin statement of second law of thermodynamics |
|
Answer» The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is IMPOSSIBLE to DEVISE a cyclically operating heat engine, the effect of which is to absorb energy in the FORM of heat from a single thermal RESERVOIR and to deliver an equivalent amount of work.The Carnot efficiency depends only on the temperature of the hot source and the cold sink. Carnot efficiency describes the maximum thermal efficiency that a heat engine can achieve as permitted by the Second Law of Thermodynamics. The law was derived by Sadi Carnot in 1824.The Kelvin-Planck statement is: “it is impossible for any device that operates in a cycle to receive heat from a single reservoir and produce a net amount of work.” Another common statement is the Clausius statement: “It is impossible to construct a device that operates in a cycle and produces no effect other than the ... |

A stone tied to the end of a string 100 cm long is whirled in a horizontal circle at a constantspeed. If the stone makes 10 revolutions in 20 s, the angular velocity of the stone is rad/sIf the string is made 80 cm long, the angular velocity will(increase, decrease,remain the same) |
|
Answer» Answer: 1800 rad/s Explanation: Perimeter of revolution of 100 cm STING = (2*π *100) total angles for 10 revolution = 2*180*10*100 = 360000 rad ANGULAR velocity= (360000/20)= 18000 rad/s If the string is made 80 cm LONG , the angular velocity will same because then revolution of the sting increases. |

Answer» ANSWER:35 Ω EXPLANATION:We have formulae to find resistance in || connection or series connection. For series connection:For parellel connect:Here we can SEE that 6Ω and 4Ω resistors are in || connection. So let's apply formula:Now this combination of resistors Rp and 21.6 Ω resistor and also 11 Ω resistors are in series combination. So let's apply formula for series combination of resistors.Hence the total effective resistance in circuit is 35Ω.ADDITIONAL INFORMATION:What is resistance? → The ability of a CONDUCTOR by which it opposes the flow of current is called resistance. It's S.I. unit is Ω(Ohm). Ohm's Law:-According to ohm's law, the POTENTIAL difference across two TERMINALS is directly proportional to the current flowing through the conductor. => V∝I After we remove sign of PROPORTIONALITY we have to apply constant value. => V=IR Please note that here R refers to resistance and it is a constant value. |
