    Distance, velocity & Acceleration

    2as=vf^2-vi^2 sorry dont know that it's constant acceleration equation

    Distance, velocity & Acceleration

    not constant acceleration with constant "Velocity" and if velocity is constant acceleration is always ZERO

    Distance, velocity & Acceleration

    but if i use equation of motion 2as=vf^2-vi^2 it give me some answer like 2.78m/s^2 :confused:

    Distance, velocity & Acceleration

    But how ? :uhh:

    Distance, velocity & Acceleration

    taking derivation of distance equation is easy as every body knows. differentiating distance we get velocity and differentiating velocity we get acceleration but if a bird fly from one tree to another of distance 50m in 3 sec. we can get it's velocity by v=s/t but how can we get it's...

    What is slope?

    Hello! What is slope. Is it rate of "average change" or "rate of instantaneous" change? Please elaborate

    SCR and Diode are Active or Passive Components?

    but i read somewhere on wikiuniversity.com that those components that supply power like battery etc are active components and those components that absorb or dissipate power. In SCR we basically control the triggering pulse so get desired power/output! it's mean if firing angle is 90deg then...

    L1 and L2 cache? Question

    Hello! According to many sites L1 is internal cache and Level 2 cache, cache memory that is external to the microprocessor. but according to this intel core2duo box (photo) , intel is selling this L2 cache on processor not on another chip. http://i40.tinypic.com/i4fu4n.jpg why is...

    Ground is always considered at 0 Volt?

    because i tested this thing with a software livewire 1.1 . the bulb glows if one battery provides 15 v and other 5v. And as there is a difference of 10 volts.

    Ground is always considered at 0 Volt?

    and if one source offers 5 volt and other offers 15 volt ? will bulb glow? because now there is a potential difference as it's called voltages!

    How to calculate displacement from distance?

    i want to do it mathematically not using google earth. is there any formula to find displacement from distance? suppose if i use helicopter how would i have to cover from islamabad to Sialkot?

    How to calculate displacement from distance?

    the distance from Islamabad to my hometown "sialkot" is 300km. if i use helicopter what would be the displacement ? Thank you!
  19. O

    How could this possible?

    ohhhh! got that one! you mean there is no current flowing so voltmeter is telling the source voltages 220. and there is no voltage drop? got that one! thank you !
  20. O

    How could this possible?

    but the circuit is open so there is no current flowing v=IR I=0A so v=0*any Resistance = 0volt but software is saying 200. it's contrary with the theories that we read before in book. on thing more voltmeter is always applied in parallel with the load here in pic the voltmeter is not applied...

    How could this possible?

    actually this question was asked by our teacher in exams i answered 0 volts but when i checked it with a software livewire 1.11 it answers 220 V who is rite?
  22. O

    How could this possible?

    As every body knows in series voltage drops and voltmeter is applied in parallel but look at this image . as the circuit is broken and voltmeter is applied but still Vmeter is showing 220V? how?

    Circuit analysis problem

    why the author is using negative sign there? And here the problem is different the author is using different current flow signs and one answer is positive and other is negative why is this so? See this? http://i42.tinypic.com/2rqdj5w.jpg
