Answer:
D is the correct answer! Hope this helps you!!!!
Explanation:
Answer:
0.02896 kg/s
Explanation:
= Initial displacement = 0.5 m
= Final displacement = 0.1 m
t = Time taken = 0.5 s
m = Mass of object = 45 g
Displacement is given by
At maximum displacement
The magnitude of the damping coefficient is 0.02896 kg/s
Answer:
Angle of incidence ray
Explanation:
The way light reflects off a smooth surface is described by the law of reflection. This law states that the angle of reflection equals the ANGLE OF INCIDENCE RAY.
This is because, when light is reflected off a smooth surface, the light is reflected by all the points that is present on that smooth surface.
Therefore the speed at which the light rays falls on the smooth surface is the same as the speed at which the light ray is reflected back. Due to their speed been the same, the distance of the incidence ray would also be the same as the distance of the reflected ray.
Hence the angle of incidence = angle of reflection.
