Why is nichrome wire used in an electric component? |
|
Answer» ong>ANSWER: Nichrome is USED for making heating element of electrical appliances. Because nichrome does not oxidize and burn easily at high temperature i.e.it has higher melting and boiling point than METALS. THUS it does not melt even when a LARGE amount of heat is produced due to passage of current. |

8: A balloon is inflated in a cold room. When the room becomes much warmer the balloon becomeslarger. How does the behaviour of the air molecules in the balloonexplain this?A) The molecules become largerB) The molecules evaporateC) The molecules move more quickD) The molecules repel each other. |
|
Answer» ONG>Answer: C ) the molecules move more quick. Explanation: Due to INCREASE in surrounding HEAT, the kinetic energy of air molecules increase and they start moving more quickly. The interparticular collisons and collison with balloon's inner wall EXERTS pressure on the balloon from inside, thus increasing the SIZE of balloon. Thanks, have a great day ahead! |

(d) None 133. Two bodies 'A' and 'B' have velocities in theratio of 2 : 1 mass of body A is half of the mass ofbody 'B' the kinetic energies of 'A' and 'B' are inthe ratio of |
|
Answer» GIVEN : • Two bodies 'A' and 'B' have VELOCITIES in the ratio of 2 : 1. • Mass of body A is half of the mass of body 'B'. To calculate :• The ratio of kinetic energies of A and B. Calculation :As velocities of 'A' and 'B' are in the ratio of 2 : 1. So, Let , • Velocity of body A = 2v • Velocity of body B = 1v or v Also, let US assume , • Mass of body B = m So, as per the given question mass of body A is half of the mass of body 'B'.
Now, let's calculate the ratio of the kinetic energies of 'A' and 'B' . Kinetic Energy of Body A :We know that, • K.E = Kinetic Energy • m = mass • v = velocity Here, ✰ Mass of A = ✰ Velocity of A = 2v Substituting values, Kinetic Energy of Body B :We know that, • K.E = Kinetic Energy • m = mass • v = velocity Here, ✰ Mass of B = m ✰ Velocity of B = v Substituting values, Calculating Ratio :Therefore, the kinetic energies of 'A' and 'B' are in the ratio of 2 : 1. |

Answer» ong>Answer: This lecture note is based on the textbook # 1. Electric MACHINERY - A.E. Fitzgerald, Charles Kingsley, Jr., Stephen D. Umans- 6th edition- Mc Graw Hill series in Electrical Engineering. Power and Energy The objective of this course is to study the DEVICES used in the interconversion of electric and mechanical energy, with emphasis placed on electromagnetic rotating machinery. The transformer, although not an electromechanical-energy-conversion device, is an important component of the overall energy-conversion process. Practically all transformers and electric machinery use ferro-magnetic material for shaping and directing the magnetic fields that acts as the medium for transferring and converting energy. Permanent-magnet materials are also widely used. The ability to analyze and describe systems containing magnetic materials is essential for DESIGNING and understanding electromechanical-energy-conversion devices. Explanation: |

the initial amount of carbon 14 is 100g and the amount of carbon 14 dropped to 1 g after decay process.the half line of carbon 14 is 5,730 y.calculate the time taken to complete this decay process |
|
Answer» ong>Given info : the INITIAL amount of CARBON 14 is 100g and the amount of carbon 14 dropped to 1 g after decay process and the half line of carbon 14 is 5,730 yrs. To find : The TIME taken to COMPLETE this decay process is ... solution : using half life equation, T½ = ln2/k where k is decay constant given half life, T½ = 5730 yrs so 5730 = ln2/k ⇒k = ln2/5730 ....(1) initial amount of carbon 14, N₀ = 100g final amount of it, N = 1G using decay equation, N = N₀e^(-kt) ⇒1 = 100 × e^(-kt) ⇒ln(1/100) = -kt ⇒ln(100) = kt ⇒t = ln(100)/{ln2/5730} = 5730 × ln(100)/ln2 = 38069.3 yrs Therefore the time taken to complete the decay process is 38069.3 yrs |

average velocity of a particle is 20m/s for time t . what should be the velocity of the particle for the next 2t seconds so that average speed is 10m/s |
|
Answer» Given - Average velocity = 20 m/s for time t . TOTAL time = t + 2t seconds => 3t seconds Average speed = 10 m/s To find -=> Velocity for next 2t seconds so that average speed is 10 m/s . Concepts/Formulae Used -» » Note -=> We have assumed distance and displacement to be the same here since it is rectilinear motion in a straight line. => So, we can interchangeably refer to the LET's Solve -» Values that we already have -=> We already know that the total time is 3t seconds. => We also know that the Average speed is 10 m/s . » For total distance -=> Total distance = (distance COVERED in time t) + (distance covered in time 2t) .
=> Average velocity = 20 m/s => Time = t seconds => => Distance = 20t metres
=> Let velocity for this be V m/s . => Time = 2t seconds => => Distance = 2t * v metres Total distance = 20t + 2tv => 2t(10+v) metres » Finding the value of 'v' -Total time = 3t seconds Total distance = 2t(10 + v) metres Average speed = 10 m/s => => => => 30 = 20 + 2v => 30-20 = 2v => 10 = 2v => 2v = 10 => v = 10/2 => v = 5 m/s Answer -=> The velocity of the PARTICLE for the next 2t seconds should be 5 m/s . |
