I don't know what's the appropriate title for my question but here it is:
What's the reference we consider to measure the speed with respect to when we say that as the speed of a moving object approaches the speed of light the time becomes slower in the frame of this moving object.
How can find the resonant frequency of small objects like dust particles?
What factors affect the resonant frequency?
And is resonant frequency dependent on size?
i.e. if the resonant frequency of 1 cm3 of glass is some certain value, would it be the same for a larger size?
I watched a documentary about Quantum mechanics.
There's a phenomenon which Einstien called "spooky action at a distance" states that two electrons appeared in the same event are related to each other in a spooky way,which means that if one of them has a specific state then the other one will...
if I heat a resistor, it will reach a specific temperature and keep it.
because as temperature increases the resistance decreases, so reducing the power absorbed.
is that true?
and how to calculate how much current and voltage I have to deliver to reach a specific temperature?
I have a problem with understanding the concepts of "object oriented programming"
I do not know what is an instance, object, method,interface...
I have read many examples from the real world
but I need a sample code with labeled instance, object, method, interface
I wish the idea is clear
In a ferromagnetic core of a transformer
why could breakdown happen if we reach "over_saturation"
in other words:
magnetic flux could make breakdown in some material just like electric current
how does that happen?
I read in "The Theory of Everything" of Stephen Hawking that all of the galaxies are running away from ours.
That made me think that the Milky Way is the center of universe, since each galaxy is running away from us(like waves on the surface of water centered at one point which is the Milky...
