Question:
Set up systems of equations and solve by any appropriate method. All numbers are accurate to at least two significant digits.
The power (in W) dissipated in an electric resistance (in Ω) equals the resistance times the square of the current (in A). If1.0 A flows through resistance R1 and 3.0 A flows through resistanceR2.the total power dissipated is 14.0 W. If 3.0 A flows through R1 and 1.0 A flows through R2, the total power dissipated is 6.0 W. Find R1 and R2.
Step by Step Answer:
Let R1 and R2 be the resistances in ohms of the two resistors Let I1 and I2 be the currents in amper...View the full answer

The square of a number is the result of multiplying that number by itself. This is also known as \"raising a number to the power of 2\" or \"squaring a number\". The concept of squaring a number is important in many areas of mathematics and science, including geometry, trigonometry, and physics. It is also used in computer programming and data analysis. The square of a number is always positive, except for the square of 0, which is 0. When a negative number is squared, the result is positive. For example, the square of -3 is 9, since (-3) x (-3) = 9. To square a two-digit number, you can use the following formula: (A x 10 + B)^2 = A^2 x 100 + 2AB x 10 + B^2 Where A represents the tens digit and B represents the ones digit of the two-digit number. In this video, you can learn a fascinating math technique to quickly compute the square of any two-digit number. This trick involves three simple steps that enable you to arrive at the answer in a matter of seconds. The video demonstrates this method using three different examples, and you can try it out yourself and share your score in the comments section. You can also see how other students are performing using this technique.
