The gravitational force between Mars and the Sun is 
Explanation:
The magnitude of the gravitational force between two objects is given by  the equation:
 
where
 is the gravitational constant
 is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
In this problem, we have:
 is the mass of the Sun
 is the mass of the Sun
 is the mass of Mars
 is the mass of Mars
 is the average distance Mars-Sun
 is the average distance Mars-Sun
Substituting into the equation, we find the gravitational force:

So, the closest answer is

Answer:
doubled
Explanation:
F=ma1----------(1)
2F = ma2-------(2)
Divide 2nd equation by 1st one
we get a1×2=a2
 
        
             
        
        
        
Answer:
a)   F = 3.2 10⁻¹⁰ N
, b)       v = 9.9 10⁷ m / s
Explanation:
a) The electric force is
        F = q E
The electric field is related to the potential reference
      V = E d
      E = V / d
Let's replace
     F = e V / d
Let's calculate
     F = 1.6 10⁻¹⁹ 28 10³ / 1.4 10⁻²
     F = 3.2 10⁻¹⁰ N
b) For this part we can use kinematics
           v² = v₀ + 2 a d
           v = √ 2 ad
Acceleration can be found with Newton's second law
         e V / d = m a
         a = e / m V / d
         a = 1.6 10⁻¹⁹ / 9.1 10⁻³¹ 28 10³ / 1.4 10⁻²
         a = 3,516 10⁻¹⁷ m / s²
Let's calculate the speed
        v = √ (2 3,516 10¹⁷ 1.4 10⁻²)
        v = √ (98,448 10¹⁴)
        v = 9.9 10⁷ m / s
 
        
             
        
        
        
Answer:
stars will emit more light due to their Luminosity, so they look very bright.
Explanation:
Luminous refers to..,
- The total amount of energy radiated by a star or other celestial object per second. 
- Therefore it is the power output of a star.
Most of the really bright stars in our sky are not that very close to us yet they look bright because of the Luminosity of the star.
These stars are intrinsically so luminous.
A star's power output across all wavelengths is called its bolometric luminosity.
A star with large luminosity will have more measure of radiated electromagnetic power meaning.
so it will emit more light than a low luminosity star.
Hence,
those stars can easily be seen even across great distance.
