A new roller coaster is advertised as having a perfectly efficient (energy is conserved) first drop without the presence of an additional applied force. Upon riding this roller coaster, a group of students question whether the roller coaster is actually perfectly efficient and want to design an experiment to test this question. The students hypothesized that inclined surfaces approach perfect efficiency as the surface increases in steepness. (The image below is not to scale and is included to provide a visual anchor.)  A student runs the experiment as described in parts a-c. The student concludes that error occurred when running the experiment because the data shows the steepest incline tested was more than 100% efficient, violating a fundamental law in physics. Write a paragraph that identifies the physics law that appears to have been violated and defines the law, explain what the student’s results would mean and how they are a violation of the identified principle, and describes an error that could have occurred during the experiment to lead to these results.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
