Newtons law of gravitation is called the universal law of gravitation because it is applicable for all masses at all distances, independent of the medium.
M=2.45 because you multiply out the equation on the right and divide by 10
Answer:
When light incident at angle more than critical angle then whole beam of light will get reflected at same angle into the same medium
So correct answer is
Option D
Explanation:
Critical angle is the maximum angle of incidence for which light shows the phenomenon of refraction of light
Here light bends at 90 degree angle when light incident at critical angle
Now if the incident light is more than the critical angle then light will follow the rules of reflection and all light rays will get reflected at same angle as that of angle of incidence
So here we can say that correct answer is
Option D
Answer:
The answer to that is C. natural gas
