Corrosive. It’s something that tends to cause corrosion, and it means to destroy or damage things slowly by chemical action.
Answer:
F = 85.24 N
T = 30.84 N
Explanation:
The parameters given are
Mass of crates = m₁ = 3 kg and m₂ = 5 kg
Component of masses acting along the plane = mgsin(θ)
Which gives;
F - (3×9.81×sin(30) + 10 + 5×9.81×sin(30) + 17) = m×a
So that we have;
2 = (F - 66.24)(3 + 5)
F = 16 + 66.24 = 85.24 N
The tension T between the crates = F × m₁/(m₁+m₂) = 85.24 × 3/(3+5) = 30.84 N
Snell's law.

1=incident
2=refracted
Since it's coming out of the amethyst into air:
n1=1.55
n2=1.0003

=

°
Substituting back into Snell's equation we get

so the angle is

°
