When thermal energy of a substance increases, it's entropy(randomness) & Kinetic energy increases.
For more appropriate answer, you should put the options 'cause there could be more than one answer for this question.
Answer:
Explanation:
horizontal is zero slope, and the vertical is undefined
Um you should putting it in a object that it can fill then go from there
They all have the same aphelion distances
To solve this problem we will resort to the concept of angle of incidence and refraction.
Since it is a reflection on a mirror, the angle provided for refraction will be equal to that of the incidence, that is, 25 °
The angle of reflation is always perpendicular to the surface so it is necessary to find the angle with respect to it.


Therefore the angle of the reflected beam of light made with the surface normal is 65°
