Answer:

If the stars are about the same  size and brightness then the earth must be nearer to the stat that appears brighter, The stars movement, nearer or farther,  would only effect the frequency received (redshift).

Answer:

D- The earth is closer to the bright star

Explanation:

If two stars have SAME brightness and size then that means the only point of difference is distance . Earth should be closer to the brighter star for the star to be bright.

Calculate the force of gravity on the 0.60- kg mass if it were 1.3×107 m above Earth's surface (that is, if it were three Earth
nignag [31]
The gravitational force between two objects is given by:
F=G \frac{m_1 m_2}{r^2}
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is their separation

In this problem, the first object has a mass of m_1=0.60 kg, while the second "object" is the Earth, with mass m_2=5.97 \cdot 10^{24}kg. The distance of the object from the Earth's center is r=1.3 \cdot 10^7 m; if we substitute these numbers into the equation, we find the force of gravity exerted by the Earth on the mass of 0.60 kg:
F=G \frac{m_1m_2}{r^2}=(6.67\cdot 10^{-11}) \frac{(0.60 kg)(5.97 \cdot 10^{24} kg)}{(1.3 \cdot 10^7 m)^2}=  1.41 N

Fault block mountains form when large blocks of crust are and tilted along normal faults
Katarina [22]
Fault block mountains form when large blocks of crust are uplifted and tilted along normal faults. The uplifted blocks are called block mountains. They are formed by the movement of large crustal blocks<span> when forces in the Earth's crust pull it apart. Some parts of the Earth are pushed upward and others collapse down.</span>

Why are TV shows nowadays so boring?
Anna [14]

The answer is a matter of opinion, and you're going to get different answers
from different people.  Here's <u>my</u> take on it:

The writers, producers and advertising sponsors of these shows certainly
don't think they're boring.  And <em><u>definitely</u></em> neither do the TV networks that
decide which ones to broadcast. 

I'm not trying to say "The experts don't think they're boring, so you must
be wrong".  I'm trying to say that different people have different opinions
about the same shows, and in <em>your</em> case,<em> you</em> find them boring.

My conclusion is this: 
I think you're finding TV shows boring nowadays because you're growing
as a person.  You've grown, developed, and matured to the point where
you're above the level of audience that the shows are pitched for.  That's
a very good thing !

You're sad because you used to get pleasure and entertainment from TV,
and now it doesn't give you those things.  That's like losing an old friend,
that you used to have such fun playing with, but he just doesn't do it for
you any more.

Now that you've grown up, you've made new friends.  With them, you do
things that you wouldn't even understand with your younger friends.  And
you develop new interests, like ... I don't know ... books, movies, hobbies,
your church, your profession, learning new things, developing new skills,
exercising your brain, writing, volunteer work, ham radio, building fine
furniture, singing, learning to write music, raising tropical plants, sculpture,
politics ... whatever turns you on.  Some people never grow past the stage
where staring at the tube is all they need in life, because they don't have
what it takes to be interested in anything else.  Those are the people that
TV is aimed at.  But you have more, and that's why TV isn't enough for you.

There are other possible reasons why TV bores you.  But until I know more
about you, I think it's a very, very good sign.
