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

Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes a time of 2.70 s for the boat to travel from its highest point to its lowest, a total distance of 0.700 m. the fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. a. how fast are the waves traveling? b. what is the amplitude a of each wave?
