Answer:
b) normal
Explanation:
The angle of refraction (transmission) Θt is the angle between the refracted ray and the normal N'. 2. When a light ray hits a surface normally, the angle between the incident ray and the normal is 0, so Θi = 0. Since the angle of reflection equals the angle of incidence, Θr= 0.
Answer:
0.2943 Nm
Explanation:
Work done is given a the product of force and diatance moved and expressed by the formula
W=Fd
Here W represent work, F is applied force and d is perpendicular distance
Also, we know that F=mg where m is the mass of an object and g is acceleration due to gravity. Substituting this back into the initial equation then
W=mgd
Taking acceleration due to gravity as 9.81 m/s2 and substituting mass with 0.1 kg and distance with 0.3 m then
W=0.1*9.81*0.3=0.2943 Nm

Explanation:
Answer:
B as distance increase force decrease, but it is not a linear relationship.
