Answer: if the heat energy is wasted, then, energy is lost forever.
Explanation: According to conservative of energy, which state that energy is neither created nor destroyed but only convert from one form to another.
The energy which should have been used in one form has been converted to heat energy which could have been used for for thing or the other, if there is nothing the heat energy can be used for, then the energy is wasted. This is tantamount to being lost forever.

U need an insulator to prevent the shock passing through , that's why there is a plastic sheet covering the copper wires so that it can prevent the electricity passing through as plastic is an insulator and does not conduct electricity
The object’s mass will be 600 grams on the moon. If you meant it’s weight, it will be 1/6 that of on Earth while on the moon.
The answer is "iron fusion".
In fact, initially all stars burn hydrogen through nuclear fusion. As they run out of hydrogen, they start to burn the next heavier element, which is helium. The very massive stars continue this cycle, and when they run out of helium they start to burn the heavier elements until reaching iron. This element represents the end of the chain, because nuclear fusion of iron does not release energy, but it absorbs energy. This means that the star can't produce energy anymore and eventually it collapses.
