The ammeter below shows the current produced by a series of solar cells that contain zinc plates being used to power a simple series circuit.

if the circuit’s resistance is 0.2 ω, what voltage is supplied by the cells?

a) 750 v

b) 15 v

c) 3 v

d) 25 v

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

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
