The magnitude of the average velocity of a particle that moves from a point x = 3 cm, y = 10 cm and z = -4 cm to another point x=21 cm, y = 16 cm and z = 29 cm in time interval of 3 seconds is:

Gunpowder residue is most likely to show up where on a shooters hands

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

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 !
