Assume you've just parked your 4840 kg car on the side of a road with a 12-degree slope and you want to calculate the forces to make sure it doesn't slide down the hill. assume the static friction coefficient is 0.3 and the kinetic friction coefficient is 0.15. calculate the magnitude of gravity, normal force, and friction force.

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

Most of the volume of an atom is occupied by the
