the constant value for speed of light is 3x10to the 7 m/sec. what is the mass equivalent of 100000 N-m of energy
e=mc^2
solve for m
I agree with san but the speed of light is 3E8 m/s

To find the mass equivalent of energy, we can use Einstein's famous equation, E=mc^2, where E represents energy, m represents mass, and c represents the speed of light.
Given that the speed of light is 3x10^8 m/s and the energy is 100,000 N-m, we can calculate the mass equivalent as follows:
Step 1: Convert the given energy from N-m to joules (J). Since 1 J = 1 N-m, the energy remains the same.
Energy (E) = 100,000 J
Step 2: Rearrange the equation E=mc^2 to solve for mass (m).
m = E / c^2
Step 3: Substitute the values into the equation.
m = 100,000 J / (3x10^8 m/s)^2
Step 4: Simplify.
m = 100,000 J / 9x10^16 m^2/s^2
m = 1.11x10^-8 kg
Therefore, the mass equivalent of 100,000 N-m of energy is approximately 1.11x10^-8 kg.
