What is a zero pair? The correct answer and explanation is: A zero pair is a pair of numbers that add up to zero. These numbers are opposites of each other, meaning one number is the negative of the other. For example, (+3) and (-3) form a zero pair, as they sum to zero. Similarly,

The distance between two telephone poles is 50.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.200 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire. The correct answer and explanation
