9 1a: Fill & Download for Free

In series circuit, current remains same in all resistances.Current I = V/R = 9/9 = 1AHere connection are in series hence 1A current flows through 4 ohm resistor and also 1A current flows through all resistors

y = -4x+15 …(1)y = -(7/2)x + 12 …(2)Since in both equations, the LHS is y, just equate the RHS of the two equations to solve for x. Thus-4x+15 = -(7/2)x + 12-8x + 30 = -7x + 24, or7x-8x = 24–30, or-x = -6, orx = 6.Check: Put x=6 in both the equations y = -24+15 = -9 …(1a)y = -(7/2)*6 + 12= -21+12 = -9…(2a) CorrectAnswer: x = 6.

I am a frequent flyer and fly 6-8 times a month on various official engagements. However when it comes to personal travel, I prefer travelling in 1A class rather than in flights the reasons being:1. Travelling in 1A is much more comfortable than sitting in flights. You have wide comfortable seats and can even lie in full flat bed when you wish to.[Image source: Trip Report: 16561 YPR – KCVL AC Express by First AC]2. You can enjoy complete privacy along with your family as you close the door. In aeroplane, you even need to compete for the armrest![Image source:Get Comfortable On Flights With SeatGuru]3. You feel special travelling in highest class of railways than travelling in Economy (lowest) class in aeroplane.[Image source: https://www.flickr.com/photos/vadakkus/10135504104]4. You don't need to go through the airport hassles like collecting boarding pass, dropping luggage, going through security, waiting to collect baggage at conveyor belts...[Image source: Soft skills training for CISF personnel at IGI Airport]5. You can carry lot more and heavier baggage than in aircraft and that too an attendant is there to help you with putting them in place and carrying them out to the platform while travelling in 1A class.[Image source:Baggage Information]6. There are minimal restrictions in carrying whatever you wish to.. from pickles to glass articles and you are sure they would reach safely.[Image source:Security, Liquids, Banned items - PARIS-CDG CHARLES de GAULLE AIRPORT]7. Pressure difference causes ear pains to many in flight, babies/children often gets uncomfortable. Such is not the case with trains.. Once the door is closed, children are free to move inside the cabin.[Image Source: 9 Important Travel Updates For Frequent Indian Railways Customers - The News Geeks (TNG)]8. Many first AC coaches have bathrooms for taking bath, even fitted with geysers. That is quite a relief for people travelling long distance.[Video source: Youtube]9. Mobile phone and Wifi works inside running trains, which is a good way to keep connected with people and also complete work related communications. Mobile connections and wifi do not work when aircraft is flying.[Image source: WiFi Terms & Conditions]10. Finally, one doesn't need to fasten seat belts while travelling through bad weathers!![Image source: What do the new rules on seat belt extenders mean for me?]When priority is comfort and not time, 1A class in train is certainly a better deal than flights.Edit 1: Edited and added point 9.
