Answer:
The angle of the corresponding refracted ray is 34.84°
Explanation:
Given that,
Refractive index of water n= 1.33
Refractive index of glass n= 1.52
Incident angle = 30.0°
We need to calculate the refracted angle
Using formula of Snell's law
Put the value into the formula
Hence, The angle of the corresponding refracted ray is 34.84°

Explanation:
A) The work done by gravity is zero because displacement and the gravitational force are perpendicular to each other.
W= FS cosθ
θ= 90 ⇒cos90 = 0 ⇒W= 0
B) work done by tension
W= Tcosθ×S= 5cos30×2.30= 10J
C) Work done by friction force
W= f×s=1×2.30= 2.30 J
D) Work done by normal force is Zero because the displacement and the normal force are perpendicular to each other.
E) The net work done= Work done by tension in the rope - frictional work
=10-2.30= 7.7 J
Answer:Since the plane velocity and the wind velocity form a right triangle when added together in head-to-tail fashion, the angle between the resultant vector and the southward vector can be determined using the sine, cosine, or tangent functions. The tangent function can be used; this is shown below:
