An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Without sufficient information about parallelogram ABCD, it's impossible to determine the dimensions of the surrounding rectangle. The problem lacks necessary details to provide a definitive answer.
Explanation
Analyze the problem The problem describes a method to find the area of a parallelogram by surrounding it with a rectangle and subtracting the areas of the corner triangles. The question asks which of the given rectangle dimensions is appropriate for this method. Without knowing the shape and size of the parallelogram ABCD, it is impossible to determine the correct dimensions of the surrounding rectangle. The problem is missing information about the parallelogram ABCD. Therefore, it is not possible to determine the dimensions of the rectangle. We cannot answer the question without knowing the dimensions or a diagram of parallelogram ABCD.
Conclusion Since we don't have enough information about the parallelogram ABCD, we cannot determine the dimensions of the rectangle that Michael should draw.
Examples
This problem illustrates the importance of having sufficient information before attempting to solve a geometric problem. In real life, this applies to various situations, such as architectural design or land surveying, where accurate measurements and shapes are crucial for planning and execution. Without precise details, any calculations or designs would be based on guesswork, leading to potentially flawed outcomes.
Approximately 2.81 × 1 0 21 electrons flow through the electric device delivering a current of 15.0 A for 30 seconds. This is calculated by determining the total charge using the current and time, and then finding the number of electrons that correspond to that charge. Each coulomb is equivalent to about 6.242 × 1 0 18 electrons.
