    What is the minimum level of energy in quantum physics and who determined it?

    I have two questions regarding Quantom physics and energy: 1.What is the minimal quantom of energy in the universe? and How and who established it? 2.Are there theories that predict that a lower level of Quantom might exist and will be discovered/validated in the future? Who proposed the...

    Surface temperature of a Sphere

    I am facing the following interesting problem. A closed room\hall contains several identical machines in it they are fed by an electrical cable. The machines can be turned on or off. When a machine is turned on, it consumes electrical energy and as a byproduct generates heat. The heat is...

    Functional structure of Surface Heat

    Thank you for your input, I appreciate your help. I assure you that it is not a homework, it is a very serious and fundamental problem. Yes, it can be assumed that the geometry is of a sphere, and the radiation is to the outside air. The boundery (the sphere surface) is very thin and...

    Functional structure of Surface Heat

    Thank you CW, Thank you for your reply. The outside skeen is not conventional matrial but it is heat conductieve, thin and radiating. I thoght on a linear relationship too, but than measured 1 machine versus 2 mcahines on, waited long enough to reach steady state (same outside temperature)...

    Heat funnction in steady state

    I was given the following interesting question. A closed room contains several identical machines in it, they are fed by an electrical cable. The machines can be turned on or off. When a machine is turned on, it consumes electrical energy and as a by product generates heat. The heat is...
