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:
Explanation:
given ;
- coefficient of kinetic friction = 0.80
- considering the force acting in horizontal direction and from newton's 2nd law of motion;
- for vertical motion = Fn - mg = 0
- for horizontal motion = F = ma + miu mg = m( a + miu.g)
- therefore, F = miu mg where g = 9.81m/s^2
- plugging the values into the equation;
Horizontal force = 204.05N
Voltage = current * resistance
V = I*R
I = 4 A
R = 2 ohm
V = 4 A * 2 ohm
= 8 volt
