The second law of thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
Answer:
<u>B. East of NYC</u>
Explanation:
We can make this conclusion because for one reason New York City is the Northern Hemisphere, and according to the Coriolis effect <em>when objects in the Northern Hemisphere travel long distances above the ground, </em><em>they will be deflected to the right </em>as a result of earth's rotation.
Hence, going by the map of New York on the Northern Hemisphere, <em>when the (object) flight is deflected to the right, for someone in NYC it will indicate a </em><em>shift to the east of NYC</em><em> </em>since the pilot failed to take the Coriolis Effect into account.
Answer:
0.5
Explanation:
Data provided in the question:
The angle between their transmission axes, θ = 60°
Now,
We have the relation,
I₁ = I₀cos²θ
where,
I₁ is the intensity of the transmitted light
I₀ is the intensity of the incident light
on rearranging, we get
=cos²60°
or
=0.5
<u>Answer:</u>
<em>The distance between Pluto and Charon is 
</em>
<u>Explanation:</u>
Force of gravitation between two objects 
Where 
are the masses of the objects,r is the distance between the objects
G is the universal gravitational constant=
Here mass of pluto = 
mass of charon = 
Force of gravitation 
=
=
