Answer:1. A 2. The bird weighing 120gExplanation1. The ball has the greatest potential energy at position A. This is because potential energy is directly proportional to height. When the ball is at its highest point (position A), it has the maximum potential energy. As it falls, this potential energy is converted into kinetic energy.2. The bird weighing 120g has more potential energy. This is because potential energy is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height. Assuming that the height of the wire is the same for both birds, the bird with the greater mass (120g) will have more potential energy.
