The diagram shows a sealed container, which represents a closed system.
How would the system change if the container were
placed on a hot plate?
O Some kinetic energy would be produced.
O Some kinetic energy would be destroyed.
O The kinetic energy of the molecules would increase.
O The kinetic energy of the molecules would decrease.

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

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 !
