Literal Equations Homework
Solve each equation for the given variable:
1. Ohm’s Law is: 𝑉 = 𝐼𝑅, where 𝑉 is voltage in volts, 𝐼 is current in amps, and 𝑅
is resistance in Ohms. Using the equations for Ohm’s Law solve for
resistance.
2. Einstein’s equation for Theory of Special Relativity is: 𝐸 = 𝑚𝑐 2 , where 𝐸 is
kinetic energy, 𝑚 is relativistic mass, and 𝑐 2 is the speed of light. Using
Einstein’s equation, solve for relativistic mass.
3. The area of a circle is represented by: 𝐴 = 𝜋𝑟 2 , where 𝐴 is area, 𝜋 is pi, and 𝑟
is the radius of the circle. Using this equation, solve for 𝜋.
