Aroller coaster is towed up an incline at a steady speed of 0.4800 m/s by a chain parallel to the surface of the incline. the slope is 2.900%, which means that the elevation increases by 2.900 m for every 100.0 m of distance along the surface. the mass of the roller coaster is 402.3 kg. neglecting friction, what is the magnitude of the force exerted on the roller coaster by the chain?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
