Answer:
Ray reflects internally
Explanation:
Given:
Ray in oil (n1) = 1.52
Ray in water (n2) = 1.33
θ = 55.9°
Computation:
Step 1 . Find critical angel(θc)
Sinθc/Sin90° = Ray in water / Ray in oil
Sinθc/1 = 1.33/1.52
θc = 61°
Since, θ = 55.9° is smaller than θc = 61°
So, Ray reflects internally.
Answer:
Gravitation
Explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
Answer:
There are three types of material as per the condition of charge flow
1) Conductor
2) Insulator
3) Semiconductor
1) Conductors
As we know that conductors are those which offer very small resistance to the flow of charge
Resistivity of the conductors are very small
2) Insulators
These type of materials offer large resistance to the flow of charges and it will not pass the current through it
So resistivity of the insulators are large as compared to conductors
