Answer (1)
Answer:Mrs. Cruz's needle is mixed with bits of paper, and she needs to separate the needle safely from the bits of paper.Step 2: Determine the best method for separationGiven the materials involved (needle and paper), we need to find a method that takes advantage of their different properties. Needles are typically made of metal, which is ferromagnetic, meaning it can be attracted to magnets.Step 3: Choose the appropriate separation methodSince the needle is likely made of a ferromagnetic material (like iron or steel), using a magnet would be an effective way to separate it from the paper bits. The magnet would attract the needle, allowing it to be pulled away from the paper.Step 4: Select the correct answerBased on the analysis, the best method for Mrs. Cruz to separate the needle from the bits of paper is by using a magnet.sorry if its too long..
