Answer: A
Explanation:
From the figure given as attachments, the error pointing upward signifies the incident ray while the one point downwards signifies the reflected ray.
One of the laws of reflection is stated that the angle of incidence is equal to the angle of reflection.
Since the two arrows are parallel to each other, then the mirror must be perpendicular to the two arrows. That is, the incident ray and the reflected ray must be perpendicular to the mirror.
Option A is the correct answer.
Answer: Choice 1
Law of Reflection
Theta(i)=Theta(r)
Angle of incidence=Angle of reflection
It can’t be created nor destroyed although it can be changed from one form to the other

Using the division operation, the <em>number of tubes gotten by each patient </em>can be obtained by <em>dividing 20 by 5</em>. Hence, each patient will get 4 tubes of solution.
<u>Tubes of solution received</u> :
- 10 a.m = 2 tubes
- 12 p.m = 4 tubes
- 3 p.m = 8 tubes
- 6 p.m = 6 tubes
<u>Total tubes received</u> :
- (2 tubes + 4 tubes + 8 tubes + 6 tubes) = 20 tubes
- Number of patients = 5 patients
<u>Number of tubes of solution gotten by each patient</u> :
- (Total tubes of solution ÷ number of patients)
Tubes of solution per patient = (20 ÷ 5) = 4 tubes
Therefore, each patient will get 4 tubes of solution.
