If a bi-directional amplifier is used for a multi carrier trunked radio radio network is at 10watts which equal to +40dBm.
If each carrier is set at +20dBm at the output port of the amplifier, then what is the maximum number of carriers can be work together at +20dBm level at the same time by the BDA and not to degrading the signal output of each carrier at +20dBM.
How to calculate????? What other criterias define or affect the output power of the BDA setting???

I'm just curious, can you be born with something that would make you more prone to a certain martial art? Like when you're born with the capacity to grow to an amazing height...

The weird thing was for a moment I was fooling around, making random movements. Some days later I saw a video clip of a certain style of kung fu. My movements(although it was less refined) were somewhat similar to the movements I saw in that clip.
We all know that the Chinese developed this kind of martial art which leads me to my main question. Can martial arts be inherited? Like its already flowing in your veins. I'm not saying that you're already born a master in this art but just in the capacity to as if your blood carries the memories of your ancestors.

Okay this question sounds pretty stupid but it's for my assignment in geometry. It's about putting triangles in application in real life so I thought the roof might be a good one.

If you can give a better example please do so and also put why it should be triangle ^^

What surface requires the least amount of energy to travel over.. land or water? Same weight.. flat land versus plat water..

It seems like it would be water.. like it's a no-brainer.. but I have seen some things* that make me wonder.. it seems like there might be more drag from the water surface contacting the boat hull. does anyone have any definitive proof?

* I saw an episode of Mythbusters where they tried to make a boat powered by compressed air.. it was a huge failure.
