12. An object is moving in a horizontal circular path at the end of a string. The tension in the
string is 12.00 N. If the object's speed is decreased by 25%, and the length of the string
decreased by 10%, what would be the new tension (in newtons)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0a649de7-a7ff-4d39-839c-f05925276079%2F0399a4be-ebef-47c8-a28d-e80b04d6fc01%2F02hu09i_processed.jpeg&w=3840&q=75)
