Answer:
The formula which should be used is ⇒ A
Step-by-step explanation:
To solve an equation of different variables to one of these variables do that
- Write the equation and underline the variable you want to solve for it
- Separate this variable on one side and all other terms on the other sides
Let us do that with the question
∵ E = <u>m</u>c²
→ E is the total energy
→ m is the total mass
→ c² is the speed of light
∵ We need to solve the equation for the total mass m
→ We need to take c² to the other side
∵ c² is multiplied by m
∴ Divide both sides by c² to move it from the right side to the left side
∴
→ Cancel c² with c² on the right side
∴
→ Switch the two sides
∴
The formula which should be used is ⇒ A
