Explanation:
The diagram shows the light ray bending away from the normal. Light rays bend away from the normal when their speed increases. This means that in the diagram, the light ray moves from a medium in which light has a lower speed to a medium in light has a higher speed. The only choice where the speed of light increases from A to B is answer A. So that has to be the answer.

Answer:
Dencidad = 600 kg/m³
Explanation:
Dados los siguientes datos;
Lado del cubo = 10 cm a metros = 10/100 = 0,1 m
Masa = 0,6 kg
Para encontrar la densidad;
En primer lugar, determinaríamos el volumen del cubo usando la fórmula;
Volumen del cubo = lados³
Volumen del cubo = 0.1³
Volumen del cubo = 0.001 m³
Ahora, podemos encontrar la densidad usando la fórmula;
Dencidad = masa/volumen
Dencidad = 0,6/0,001
Dencidad = 600 kg/m³
