Answer:
<em>0.3c</em>
<em></em>
Explanation:
The speed of Enterprise relative to Risa is 0.8c
Relative speed of both ships as measured from Enterprise is 0.5c
therefore, relative speed of Astra to Enterprise is 0.8c - 0.5c = <em>0.3c</em>
<em>this is also the relative speed with which Astra approaches the planet Risa since Enterprise's speed was calculated relative to Risa.</em>
Use vector analysis and calculate resultant vector using Pythagoras theorem:
5^2 + 5^2 = 50
Square root of 50 = approx 7.1 km NE
Therefore the answer is D
Answer:
1.
2.
Explanation:
Polarizes axis can create two possible angles with the vertical.
first we have to find the intensity of first polarizer
which is given as



For a smaller angle for the first polarizer:
According to Malus Law



taking square root on both sides



For a larger angle for the first polarizer:
According to Malus Law


taking square root on both sides
