Explain how volt and electron volt related? |
|
Answer» Answer: Explanation: An electron volt is the AMOUNT of ENERGY needed to CHANGE the potential of a single electron by one volt. Remember, volts are a simplified way of saying “joules per coulomb”, so one electron volt = 1V * 1.6e-19 COULOMBS = 1.6e-19 joules.! |

2. How con we elicit more information in a conversation? |
|
Answer» Answer: We examine the strategic interaction between an informed expert and an uninformed DECISION maker, extending the ANALYSIS of Crawford and Sobel (Econometrica 50 (1982) 1431). We modify their model to allow for more extensive communication between the two PARTIES and show that face-to-face communication between the expert and the uninformed decision maker followed by a written report from the expert leads to improved information TRANSMISSION. In (almost) all cases, there exists an equilibrium in our modified model that ex ante Pareto dominates all of the equilibria identified by Crawford and Sobel. This remains TRUE even if the expert's bias is so great that in their model no information would be disclosed. Explanation: your answer is here |

Write a note on heat and temperature |
|
Answer» Answer: Explanation: simplest terms, temperature is how HOT or cold an object is, while heat is the energy that flows from a hotter object to a cooler one. For example, the temperature of a cup of coffee MAY feel hot if you put your hand AROUND it. It is hot because heat from the coffee is transferred to the cup |

Apply first law of thermodynamics to isochoric process and isobaric process |
|
Answer» Answer: hi friends follow me and marks as BRAINLIST Explanation: An isochoric process, also CALLED a constant-volume process, an isovolumetric process, or an isometric process, is a THERMODYNAMIC process during which the volume of the closed system undergoing such a process remains constant. An Isobaric process is a thermodynamic process in which the pressure stays constant: ΔP = 0. The heat TRANSFERRED to the system does work, but also changes the INTERNAL energy of the system. |

Derivation of heat formula( Q = m. S. ∆T ) |
|
Answer» Specific Heat formula is articulated as C=ΔQ/mΔT Where, Δ Q is the heat gained or lost, Δ T is the temperature difference. The temperature difference is given by Δ T = (Tf – Ti), where the final temperature is Tf and the INITIAL temperature is Ti . Specific Heat formula is made use of to find the specific heat of any given material, its mass, heat gained or temperature difference if some of the variables are given. It is articulated in Joule/Kg Kelvin (J/Kg K). Specific Heat SOLVED Examples Underneath are some questions based on specific heat which will be useful for you. Problem 1: Calculate the heat required to raise 0.6 Kg of sand from 30oC to 90oC? (Specific Heat of sand = 830 J/KgoC) Answer: Known: Mass of sand m = 0.6 Kg, Δ T (Temperature difference) = 90oC – 30oC = 60oC C (Specific Heat of sand) = 830 J/KgoC The specific heat is given by, C=ΔQmΔT Henceforth, Heat required is given by Q = C m Δ T = 830 J/KgoC × 0.6 Kg × 60oC = 29880 J. Problem 2: Compute the temperature difference if 50 Kg of water absorbs 500 K J of heat? Answer: Known: m (Mass) = 50 Kg, Q (Heat transfer) = 500 KJ, C (Specific Heat of water) = 4.2 × 103 J/KgoC |
