Asingly-charged ion enters a velocity selector that has a 0.18-t magnetic field perpendicular to an electric field of 1.6 kv/m, with both fields perpendicular to the velocity of the ion. the same magnetic field is then used to deflect the ion into a circular path of radius 12.5 cm. what velocity was selected by the velocity selector?

What happens to the light rays when they hit the specimen?

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 !

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?
