Final answer:
To find the value of each variable, identify known values, use the correct equations, solve for unknowns and carefully check your answers.
Step-by-step explanation:
To find the value of each variable, we begin by identifying the known values and the variables we need to solve for. This involves listing all known values, which can be facilitated by using a table. The next step is to hold each factor on the left-hand side of the equation constant and consider them one at a time.
Once we have identified what we need to solve for, we proceed by selecting the appropriate equation. The process continues as we plug the knowns into the equation and solve for the unknowns. Solving simultaneous equations might be necessary, which requires algebraic manipulation and careful checking through each step.
After solving, we evaluate the expressions for the unknown quantities and check the final answer to ensure the numerical values and units are correct. If there appears to be a discrepancy, we revisit the previous steps to locate and correct the mistake. To further validate our solution, we can independently check our numerical answers by different methods such as changing the pivot point in a physics problem.
