A nucleus has A nucleus has more energy than its component neutrons and protons have. less energy than its component neutrons and protons have. more energy than its component neutrons and protons have when the nucleus is at rest but less energy than when it is moving. the same energy as its component neutrons and protons have.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Wind and moving water provide energy. question 1 options: chemical mechanical thermal none of the above
