If you type in google.com any 2 or 3 digit numbers combinations before "new cases" for example "312 new cases" into google there will always be a result with a covid19 article correlating with the number... why is that?
But if the mother bear is familiar and comfortable around you... would they still try to attack you? Of course any wild animal will attack someone if they just run and try to hurt there cubs.
This might be a little unsettling for some and I don't know exactly where to post this but here we go...
What would the reaction of say a mother cat be in the moment if you where to take one of it's baby and kill it in front of them? Would they attack you? Would they show some signs of sadness...
Another thing, do carrier waves ever carry any "Useful information" or is the information only in the side bands?
When I tune my radio to a particular frequency, that frequency is called the carrier right?
So from what I understand right now is that the carrier is modulated by an input signal...
Is the carrier wave modulated or in other words "modified" with the information signal? If so how exactly is this done? I can't find or maybe I am looking at the wrong things but I don't understand how this is done.
I know that AM is modulated with the amplitude and FM is modulated by the...
My brain hurts already, I don't know if I am making sense anymore.
I'm trying my best here, let's say you have a song or information you want to send out... this information is transformed into electrical signals that then radiates radio waves from the antenna... after this part I am a little...
I see, I should've of used these for examples instead? 10 Ghz to 30 Ghz and 5 Khz to 10 Khz? Does this make more sense?
The amplitude and frequency of the wave WITHIN bands is what determines information or speech correct?
Thank you all for the help by the way.
Just wondering if I understand "radio bands" correctly I am not sure I do.
Lets say you have a radio band of 10 GHZ to 30 GHZ and another from 10 HERTZ to 30 HERTZ, the information or a song transmitted will sound the same in those two ranges, the only thing that matters is the amplitude or the...
"It does not necessarily have to be biological, dyes inks ores oxides and certain salts all can be coloured as well as trees flowers people and birds. "And all of those mentioned things is the result of chromophores?
If the color of an object isn't because of heat is it chromophores?
