Astuntman drives a car with a mass of 1500 kg on a drawbridge. the car accelerates with a constant force of 10,000 n. while he is driving, the drawbridge is raised to an incline of 30°. what is the car's new acceleration on this incline, ignoring the force due to air resistance? (recall that g=9.8 m/s^2)

What is an aquifer for science class

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
