Answer:
Angle of Refraction = 28.9 degrees
Explanation:
<u><em>We'll use Snell's law for this. It's mathematical form is:</em></u>
=>
Where
=> and
are the refractive indexes of the air and water respectively.
<u><em>Solution:</em></u>
=> 1 * sin (40) = 1.33 * sin()
=> sin =
=> sin = 0.4821
=> = 28.9 degrees
Answer:
The ratio of the orbital time periods of A and B is
Solution:
As per the question:
The orbit of the two satellites is circular
Also,
Orbital speed of A is 2 times the orbital speed of B
(1)
Now, we know that the orbital speed of a satellite for circular orbits is given by:
where
R = Radius of the orbit
Now,
For satellite A:
Using eqn (1):
(2)
For satellite B:
(3)
Now, comparing eqn (2) and eqn (3):
