Ahiker walked a hiking trail according to the chart below. what is a possible explanation of the hiker's movement? the hiker ended up in the same place that he started. the hiker got tired and walked the slowest from 1: 00-2: 00. the hiker stopped for lunch from 11: 00-12: 00 and that slowed him down. the hiker had an easy, level trail from 11: 00-12: 00 and was able to travel the fastest during that time period.

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
