The angular momentum is conserved in this scenario because there are no external torques acting on the system. When the skater pulls her arms in, she decreases her moment of inertia, causing her angular velocity to increase in order to conserve angular momentum. This is a result of the principle of conservation of angular momentum, which states that the total angular momentum of a system remains constant if no external torques are acting on it. Therefore, in the absence of external torques, the skater's angular momentum is conserved as she pulls her arms in. **

To conserve the battery of the iPhone 13, you can start by adjusting the screen brightness to a lower level and enabling the "Auto-Brightness" feature.

No, the energy of the air is not conserved when a ball falls through the air to the ground. As the ball falls, it loses potential energy due to gravity, which is converted into kinetic energy. Additionally, some of the energy is lost to air resistance in the form of heat and sound. Therefore, the total energy of the system (ball and air) is not conserved during this process. **
