Question

The graph below represents the relationship between energy and equivalent mass from which it can be converted.
The slope of this graph represents:
Options
A speed of light squared
Correct Answer
B frequency
C wavelength
D momentum
Correct Answer

Option A is the correct answer.

Detailed Explanation

The relationship between energy (E) and equivalent mass (m) is given by Einstein's mass-energy equivalence formula: E = mc², where c is the speed of light.If we consider Energy (E) as the y-axis and Equivalent Mass (m) as the x-axis, the equation E = (c²)m is in the form y = (slope)x.Therefore, the slope of the graph representing Energy vs. Equivalent Mass is c², which is the speed of light squared.

Hint

Remember Einstein's famous equation relating mass and energy.
