Hello!! I hope someone can help me with this question. If you can explain it to me along with the CORRECT answer, and only one of you do that, I will give you brainliest! How long must a pendulum be for a swing from one side to the other to take exactly 1s here on the surface of the earth? Use 9.81m/s^2 for acceleration due to gravity.

Rules for brainliest:
-Correct answer
-if one says how to do it and another does not, the one who explained will receive brainliest
-there has to be two answers for me to give brainliest

stay positive and hope you can help! xoxo
