Salsk061 [2.6K]
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a

Which option accurately describes a scenario in which a tortoise experiences a displacement of 10 m south? A tortoise starts at
Ahat [919]

Answer:

A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

Step-by-step explanation:

Let's assume southern and eastern movement as positive and northern and western movement as negative. Since we want the displacement, starting position should not be considered.

1-) A tortoise starts at a position of 3 m south. It moves 4 m east, 2 m west, and then 3 m north.

S = -3m

E = 4 - 2 =2m

2-) A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

S= 10m

E= 10 - 10 = 0m

3-) A tortoise starts at a position of 2 m north. It moves 4 m west and then 7 m south.

S= 7m

E= -4m

4-) A tortoise starts at a position of 0 m. It moves 10 m west, 5 m east, and then 5 m south.

S= 5m

E= 5 - 10 = -5m

Analyzing all of the previous scenarios, only one presents a 10 m southern displacement, and that is when the tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.
