Final answer:
The potential energy from the complete conversion of a 50 gram mass into energy, based on Einstein's mass-energy equivalence principle, results in 4.5 x 10^15 Joules of energy.
Step-by-step explanation:
The potential energy of an object is dependent on its mass, the height it is raised to, and the acceleration due to gravity. However, if we're talking about the complete conversion of a mass into energy, it's a matter related to Einstein's mass-energy equivalence principle, which is represented by the equation E = mc2, where E is energy, m is mass, and c is the speed of light. For a mass of 50 grams (which is 0.05 kilograms), the energy obtained from complete conversion would be extraordinarily large, as the speed of light (c) is about 3.00 x 108 m/s. The calculation for this complete conversion is E = (0.05 kg) x (3.00 x 108 m/s)2, which results in 4.5 x 1015 Joules of energy. This amount of energy illustrates just how massive the energy content of matter is when it's converted entirely into energy.
