To practice problem-solving strategy 27.1: magnetic forces. a particle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, you can check your result by comparing its magnitude to the magnitude the acceleration would have if the particle's velocity had the same magnitude but it was perpendicular to the magnetic field. find the value of the expression

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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
