An electron moving through an electric field experiences an acceleration of 5800 × 103 m/s 2 . Find the magnitude of the electric force acting on the electron. The Coulomb constant is 8.98755 × 109 N · m2 /C 2 , the fundamental charge is 1.602 × 10−19 C, and the mass of the

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
