Calculate the energy equivalent of a 85kg mass.
Understand the Problem
The question seems to be implying to calculate the energy equivalent of Alex's mass using Einstein's mass-energy equivalence principle, E=mc^2. However, it's somewhat ambiguous, as simply knowing someone's mass doesn't usually translate to a question about energy. It's likely a physics question prompting for the calculation of the energy equivalent to a given mass.
Answer
The energy equivalent of an 85 kg mass is 7.63966902345e+18 Joules, using E=mc^2.
The energy equivalent of an 85 kg mass is 7.63966902345e+18 Joules. This is calculated using Einstein's mass-energy equivalence formula, E=mc^2, where E is energy, m is mass, and c is the speed of light (approximately 299,792,458 m/s).
Answer for screen readers
The energy equivalent of an 85 kg mass is 7.63966902345e+18 Joules. This is calculated using Einstein's mass-energy equivalence formula, E=mc^2, where E is energy, m is mass, and c is the speed of light (approximately 299,792,458 m/s).
More Information
The equation E=mc^2 is one of the most famous equations in physics and demonstrates that mass and energy are interchangeable. A small amount of mass can be converted into a tremendous amount of energy, as demonstrated by nuclear reactions.
Tips
A common mistake is using the wrong units for mass or the speed of light. Mass must be in kilograms (kg) and the speed of light in meters per second (m/s) to obtain energy in Joules.
