Rays of the sun are seen to make a 34.7° angle to the vertical beneath the water. at what angle above the horizon is the sun?

49.19°

Explanation:

θ₁ = Angle of incidence

θ₂ = Angle of refraction = 34.7°

n₁ = Refractive index of air = 1.0003

n₂ = Refractive index of water = 1.33

From Snell's Law

In order to find the angle of sun above horizon we have to subtract the angle

90 - 49.19 = 40.81

The sun is at an angle of 40.81° above the horizon.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
