Answer the following question given this paragraph: with a minus sign because the displacement while stopping and the force from floor are in opposite directions (cos = cos 180 = 1) . The floor removes energy from the system, so it does negative work. The kinetic energy the person has upon reaching the floor is the amount of potential energy lost by falling through height. Q: When someone falls, the kinetic energy the person has upon reaching the floor is the amount of what energy lost by falling through height? Choices: - gravitational energy - thermal energy - nuclear energy - potential energy A:
potential energy

Answer the following question given this paragraph: Nekton are living things that swim through the water. They may live at any depth, in the photic or aphotic zone. Most nekton are fish, although some are mammals. Fish have fins and streamlined bodies to help them swim. Fish also have gills to take oxygen from the water. Figure below shows examples of nekton. Q: What are the two classifications for organisms living in water? Choices: - arctan and nekton - arctan and plankton - scharwenka and plankton - nekton and plankton A:
**Answer**
nekton and plankton
