Astudent decides they would like to have hands - on experience when it comes to transformers .the student takes an iron core (square shaped )and wraps a wire around one side 10 times and call this side the primary side (so np=10). the student takes another wire and wraps it around the opposite side of the iron core 20 times and calls this the secondary side ( so ns=20) the student then hooks the primary side to a 1.50-v lab battery.
a) if the student then used a voltmeter to measure the voltage on the secondary side what voltage should the student measure .
b) if the student uses an amp-meter to measure 200-ma on the secondary side how much current was entering the primary coil ?

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 !
