If we take a steel container, fill it completely with water and seal it back (all this at sea-level), and then take it to bottom of sea, what will happen to the container? Will it be crushed? What equation should we use to relate initial and final volume? Kindly help.

yes i was thinking about that too. it will be economically unfeasible. but what if we increase the antenna area? suppose we embed antennas in all the walls and roof, like a faraday cage? will it work? could it just be enough to power up 3 bulbs and a fan? if so, it would be most useful for...
Hello everyone!
I was just thinking about whether it will be possible to utilise the energy transmitted through the radio waves to produce back electricity for a household. Most of the houses in the world are blanketed by radio waves from all directions. Will it be possible to use an antenna...
please note that the friction force also depends on the Normal reaction, which depends on cosine of the angle of inclination.
f = mg.cos(theta). So steeper the slope, lesser is the frictional force.
