The speed of light in vacuum is taken as unity. If light takes 6 min 40 s to reach the Earth from the Sun, the distance between the Sun and the Earth in new unit is: ____.
When an object is shot from the bottom of a long smooth inclined plane kept at an angle \(60 \degree\)with horizontal, it can travel a distance \(x_1\) along the plane. But when the inclination is decreased to \(30 \degree\) and the same object is shot with the same velocity, it can travel \(x_2\) distance. Then \(x_1:x_2\) will be:
