Answer:
b
Explanation:
because it fly and you need for it to drop at the right spot for them to get it
Answer:
45.93°
Explanation:
The angle of incidence is given as 32.7°
The refractive index of the water that is 
Refractive index of the air that is 
(because the refractive index of air is 1 )
We have to find the angle at which the light leave the water means angle of refraction
So according to snell's law 
r =45.93°
So the light leave the water at an angle of 45.93°
Answer:
The three best answers are:
Electric fields can be positive or negative (depending on source)
Electric fields can attrace or repel objets (assuming the object is charged)
Electric forces are strongest near the charged object E ∝ 1 / R^2
