The diagram shows an electric motor. An illustration of a coil of wire connected to a battery labeled Z. The coil is inbetween a north pole and a south pole. The coil is rotating clockwise. The point where the positive electrode of the battery is connected to it is labeled Y. The long straight with that it rotates around is labeled W. The ring with a slit that the battery is connected to is labeled X. Which part of the motor is responsible for reversing the flow of current? W X Y Z

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

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 !

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
