I don't understand how frequency multiplexing works on one cable (For example :a cable tv network that sends 100s of TV channels to a TV)I understand that we can mix frequencies, and then demultiplex them.
But how does demultiplexing happen ?
After mixing, we get a soup.(which contains the...
I am quite confused how a speaker can produce two or more different frequencies at the same time ?
Let's consider one instrument to be the thud of the kick drum
Let the second instrument be a Shakuhachi flute. (From Enigma Sadeness)
Let us have only one speaker( like in most of the...
Does that mean that the energy spent by Superman to hold a Harrier at 1m & the energy the Harrier's thrusters consume at 1m is not the same ?
I believe, how Superman holds the Harrier is important.
If he places on it on his head, and makes sure that the ground's normal, goes through this leg...
Hi, I would like to know, what is the difference between a 7 ton Harrier placed on a 1m high table, and the same 7 ton Harrier, maintaining an stationary altitude of 1 meter above the ground with its vertical thrusters ?
I both the cases, the potential energy of the Harrier is the same...
I am glad that you both understand my situation quite well :).
Can I then confirm, then that, though a vector has both magnitude & direction, it may not manifest itself in reality ?
Hi guys,
I find it quite difficult to visualize torque.
The picture I use as reference could be found here.

I have had this disk with spindle thing & had tried rotating it.
But I did not feel anything in the direction of torque.(red arrow)...
Why is that the concept of Force & Accel brought in ? :confused:
Are they not concepts that require time & happen over time OR requires time as a component ?? :rolleyes: {For eg. a push or pull happens over time and without bringing in time, the concepts of Force & Acceleration might go...
What is mass ??
Text books define it as the "amount" of substance...
You can also use some equations and toss Mass out, giving other definitions.
But my question is about the wording "amount of substance"
> What is this "amount of substance" ?
> Because "amount" refers to counting..
How...
Well,
I too want to understand the concept of "force".
I find it a bit hard to understand.
1> I don't need proofs. I just need the understanding. :cool:
2> Is 'time' a part of 'force' ?? . Can we talk about force ignoring time ?
