For the first question, the correct answer is:b. rub, will lift upExplanation: When you rub a comb on a woolen material, it creates static electricity. Holding the comb over small paper pieces will cause them to lift up due to the attraction between the charged comb and the neutral paper pieces.For the second question, the correct answer is:c. calculate, will beginExplanation: We need to calculate the resistance of the electric circuit before we begin to carry out the experiment. This ensures that we have the necessary information to proceed correctly.
