Question
The graph below represents the relationship between energy and equivalent mass from which it can be converted. The slope of this graph (with Energy on the y-axis and Equivalent Mass on the x-axis) represents:
Correct Answer
Option B is the correct answer.
Detailed Explanation
The relationship between energy (E) and equivalent mass (m) is given by Einstein's famous equation E = mc2, where c is the speed of light. If Energy (E) is plotted on the y-axis and Equivalent Mass (m) is plotted on the x-axis, the equation can be written in the form y = kx, where k is the slope. Comparing E = mc2 to y = kx, we see that the slope (k) of the graph represents c2, the speed of light squared.
Hint
Recall Einstein's mass-energy equivalence equation.
