Answer
Students built two electromagnets. The electromagnets are the same except that one has 20 wire coils around its core, and the other has 40 wire coils around its core. Which is the best comparison?(1 point) Responses The electromagnet with 20 coils will be stronger than the electromagnet with 40 coils. The electromagnet with 20 coils will be stronger than the electromagnet with 40 coils. The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils. The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils. The electromagnets will be equally strong. The electromagnets will be equally strong. The electromagnet with 40 coils will be exactly twice as strong as the electromagnet with 20 coils.
Answer
Samuel builds four electromagnets and tests them by picking up paperclips. Here are his partial results. Coils Paperclips 8 2 16 7 24 11 30 ? Which is the best prediction for the number of paperclips the electromagnet with 30 coils will pick up? (1 point) Responses 1 paperclip 1 paperclip 8 paperclips 8 paperclips 11 paperclips 11 paperclips 14 paperclips
