I agree with Sir Donis that Newtonian mechanics is sufficient over GR.Thanks sir

sir i read somewhere that massive Earth distorts spacetime as we all know but distortion is more at poles due to sperical shape of earth.This last line was the main root of confusion.

[Moderator's note: spun off from previous thread on a different topic.] how general relativity explains the variation in value of g at equator and poles? why the twist in spacetime is more at poles than equator and not viceversa

thanks for your precious time for answering sir.

thanks sir.but i wanted to know one more thing.my inverter was producing humming sound one day,the moment i slowed down my fan the sound was silent.was it due to reduced current drawn or a little bit improved power factor. is variation in current in ac circuit as well as dc circuit upon...

it has been designed for India 230v/50hz.it gets hotter if we increse its resistance through rotary switch(to position4,3,2,1),but the fan slows down.as it gets reduced voltage now.sorry if i am still not able to elaborate.

sorry the url was not uploaded.its here- maxelectrical.tradeindia.com/fan-regulator-1133953.html

http://maxelectrical.tradeindia.com/fan-regulator-1133953.html a fan regulator is a device put in series with fan to alter its speed.it can provide different value of resistance through a rotatory switch numbered 1 ,2,3,4,5.At position 5 the speed of fan is max.at 1 its min.as resistance of...

actually i searched a lot regarding this question but didnt find exact answer anywhere.some say electricity bill reduces some vice versa.do all extra voltage is dissipated as heat? in the regulator,or current drawn remains same or only partially dissipated as heat.Thanks.

yes you are correct.its only due to frequency of the supply.a capacitor after full charged behaves as open circuit due to infinite capacitive reactance when frequency is 0 say in dc

(joule per second)/ampere gives joule per Coulomb can the readings from that old car metre be callibrated to give j/c

hats off jim hardy sir your enormous experience can do anything impossible...

This example given by dale spam clearly defines everything.50J energy of ball with respect to train is 800 J if seen relative to track and is something different value if seen relative to a car moving at say 5 Km/ hr.So value of energy is not absolute. Hats off.
