The correct answer is: 2.7×10¹⁵ JExplanation:We can use Einstein's equation, E=mc², where E is energy, m is mass, and c is the speed of light. We can use this formula to determine how much energy would be available if the mass of a 0.03 kg penny was converted completely to energy.E = mc²E = (0.03 kg)(3×10⁸ m/s)²E = (0.03 kg)(9×10¹⁶ m²/s²)E = 2.7×10¹⁵ JTherefore, if the mass of a 0.03 kg penny was converted completely to energy, there would be 2.7×10¹⁵ J of energy available.
