The six statements below represent Newton's laws of motion and Kepler's three laws of planetary motion. Match the correct laws to the examples in which they apply. Use each law only once. Group of answer choices This law explains why a spaceship with no forces acting on it will continue moving even if it has no fuel. [ Choose ] For planets orbiting the Sun, period (p) and orbital distance (a) obey the relation "p squared = a cubed". For any force, there is an equal and opposite reachtion force The orbit of each planet is an ellipse, with the Sun at one focus. A line between a planet and its Sun sweeps out equal areas in equal times Force equals mass times acceleration An object moves at constant velocity if there is no net force acting on it

A closed square wire with an area of 0.02 m^2 is placed on a flat plane. A homogeneous magnetic field is applied to the plane in a direction that penetrates into the plane perpendicularly away from the reader. The magnetic field is lowered at a constant rate of 2 x 10^(-4) T/s. If the resistance of the wire used is 0.20 ohm, then the magnitude and direction of the induced current that arises is Select one : 2 x 10^-5 A clockwise 1 x 10^-5 A clockwise 1 x 10^-5 A counterclockwise 2 x 10^-5 A counterclockwise
