The ray more the incidence ray, the more will be the reflected ray. As angle of incidence is to angle of reflection.
Glare can be defined as the difficulty in seeing the object due to more brightness. The bright light such as the direct sunlight or the reflected sunlight or the headlight at the nighttime.The more the intensity the more will be glare.
Hence, the ray that will produce most glare is 70 degree.
A ray at which angle would produce the most glare is at 70 degrees. The
answer is letter D. the greater the incident of light is, the greater is its
index of refraction and thus having greater angle to produce a light ray.
Answer: Machanical advantage of the machine is 1.86
Explanation: Machanical advantage of a machine is the ratio of the Force to overcome which is the load in this case 24kg * 10= 240N to the force exerted(Effort) to overcome the load in this case 129N.
