Respuesta :
if the object, ends up with a positive charge, then it is missing electrons. if it is missing electrons, then it must have been removed form the object during the rubbing process.
The angle of refraction for the ray of light that enters the bucket of water at an angle of 17° is 12.7°
Snell's law
index of refraction (n) = Sine i / Sine r
n = Sine i / Sine r
Where
- i is the angle of incidence
- r is the angle of refraction
How to determine the refracted angle
From the question given above, the following data were obtained:
- Index of refraction (n) = 1.333
- Angle of incidence (i) = 17°
- Angle of refraction (r) =?
n = Sine i / Sine r
1.333 = Sine 17 / Sine r
Cross multiply
1.333 × Sine r = Sine 17
Divide both side by 1.333
Sine r = Sine 17 / 1.333
Sine r = 0.2193
Take the inverse of Sine
r = Sine¯¹ 0.2193
r = 12.7°
