The correct answer is
C. Light can pass through Object B faster than it can pass through Object A.
In fact, the index of refraction of a material is defined as:
where c is the speed of light in vacuum and v is the speed of light in the material. Rearranging the equation, we can write the speed of light in the material as:
So we that, the smaller the refractive index n, the greater the speed of light in the material, v. In this problem, object B has lower refractive index than object A, so light travels faster in object B.
Answer:
Increase in the intensity of pressure allows very less deformation
Explanation:
For the water the variation of pressure at any depth is directly proportional to the depth of the water above that level.
Thus, at depth greater than 60 m the intensity of pressure on ice is very high and therefore very little deformation is possible.
Hence, the transition from brittle to ductile behavior is observed.
Answer:
william h. seward secured the purchase of alaska from:
Explanation:
Explanation:
When water is boiled in the flask . Some portion of it is evaporated out . Now when cork is placed on it and is placed in the ice box . It cools down , by which the pressure inside decreases .
Due to decrease of pressure , the boiling point of water also decreases . Now it can boil at lower temperature . Thus it starts boiling at lower temperature even , when placed in the ice box .
