You hit a golf ball 30.0 meters to the south and overshoot the hole. you then hit the ball another 5.0 m to the north. the distance the ball travels is .

The distance is 35.0 m

Explanation:

- Distance corresponds to the amount of space travelled by an object, regardless of the direction of the motion. Therefore, if an object moves several times into different directions, the distance can be simply calculated by adding the distance covered during each motion.

In this case, the ball moves a first time by and a second time by , so the total distance is

- Displacement corresponds instead to the spatial difference between the starting point and the final point of the motion: since the ball here travelled 30.0 m south and 5.0 m north, we must take into account the opposite directions in the two motions, by adding a negative sign. So, the displacement of the ball is

(in the south direction)

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
