Capitolo 2, Problema 41
In Exercises 35–54, solve each formula for the specified variable. Do you recognize the formula? If so, what does it describe? E = mc2 for m
Guida verificata passo dopo passo1
Identify the formula given: \(E = mc^2\). This is Einstein's mass-energy equivalence formula, which relates energy (\(E\)) to mass (\(m\)) and the speed of light (\(c\)).
The goal is to solve the formula for the variable \(m\), which means isolating \(m\) on one side of the equation.
Start by dividing both sides of the equation by \(c^2\) to isolate \(m\): \(\frac{E}{c^2} = \frac{mc^2}{c^2}\).
Simplify the right side since \(c^2\) divided by \(c^2\) is 1, leaving \(\frac{E}{c^2} = m\).
Rewrite the equation to express \(m\) explicitly: \(m = \frac{E}{c^2}\). This shows mass as energy divided by the square of the speed of light.
