    Theres no connection just theres ##F_{mM}## in N as I said If ##N=F-ma-Ma## we get zero If I can write N I ll sove the queston.Just Idk...

  5. Al_Pa_Cone replied to the thread What pressure would a strain of 40 µε indicate?.

    I had the same problem, I stopped doing it for months and had to force myself back into it. Question 5c was a f*cker! I used...

  6. PeroK replied to the thread Relativity: Time dilation and distance calculations.

    There's a clue in classical physics. Objects have a length. In classical physics this is an invariant between reference frames. You...

  7. giulio_hep replied to the thread A Assumptions behind Maxwell's equations for constant speed.

    The question is: does the special relativity allow the universal speed to vary with time? I'd say no. Moreover I was kindly...

  8. f95toli replied to the thread have 5.19v dc want 5.00v dc ... need help please.

    I would suggest looking for 5.0V voltage references instead of a regulator; most sensors want an accurate voltage but won't draw much...

  11. windy miller liked Stephanus's post in the thread I types of time in relativity.

    Perhaps I can add. Proper time is 1 minute, 2 minutes or 1 month, 2 months, etc... So if you see a rocket travelling toward (away from...
