Change the value of the battery emf to 10.0 v, and make sure the middle resistor is set to 20 ω. use extra wire for each "leg" of the circuit so you can measure the current through all legs with the ammeter. how does the current coming out of the battery change when the switch is closed?

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

The speed of light can be used to measure the

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
