We did a lab studying resistance and ohm’s law. in my lab, my light bulb circuit element did not obey ohm’s law b/c my data did not convey a proportional relationship between voltage drop and current. how do i
if either or both of your circuit elements did not obey ohm’s law, can you think of any reasons for the non-ohmic behavior? in other words what might be happening to one or both of the elements as the applied voltage drop increases?

Identical marbles are released from the same height on each of the following four frictionless ramps . compare the speed of the marbles at the end of each ramp. explain your reasoning

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
