Answer:
r = 29.53 degrees
Explanation:
Given that,
Angle of incidence, 
We need to find the angle at which it will travel in the water. The refractive index of water is 1.33 and refractive index of air is 1. Using Snell's law as :

r is the angle of refraction

So, the ray will travel at an angle of 29.53 degrees in the water.
Answer:
The tesla is the SI unit for the magnetic field (T). One tesla is the magnetic field in which a charge of one coulomb travelling perpendicular to the magnetic field at a velocity of 1 m/s receives a force of one newton.

Answer: The Sun rotates on its axis once in about 27 days. ... The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
Explanation: I hope this helps :)
