AI Thread Summary
The mass of the disc remains unchanged when used in a disc player, as the energy output in the form of video does not alter the mass according to Einstein's equation e=mc^2. The energy produced from the disc is a result of the conversion of stored information into a visual format, not a change in the disc's mass. The question posed contains a misunderstanding of how energy and mass interact in this context. The disc's mass remains constant regardless of its function in the player. Therefore, the energy displayed on the screen does not imply a change in the mass of the disc itself.

Why the mass of disc does not changes according to Einstein's equation(e=mc^2) when we insert it inside a disc player and it shows us energy in the form of video on a tv/monitor screen.

  • I think there's something wrong in this question, can anybody point out the error with reasoning.

The disc does not change, therefore, its mass does not change.
Can you describe your reasoning in more, smaller steps?
 
Can you show the video without the TV and the disc reader being plugged in?

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
