Answer:
Refraction
Explanation:
When light passes from a rarer medium into a denser medium, it bends in the medium away from the normal. This creates the phenomenon of "apparent depth" as given in the question.
This question involves the concepts of the law of conservation of momentum and speed.
She moves with a speed of "0.41 m/s".
Applying the law of conservation of momentum to this situation, we get:

where,
m₁ = mass of shirley = 65 kg
m₂ = mass of tank = 12 kg
u₁ = initial speed of shirley = 0 m/s
u₂ = initial speed of tank = 0 m/s
v₁ = final speed of shirley = ?
v₂ = final speed of tank = 2.2 m/s
Therefore,

negative sign shows the opposite direction.
