Answer: +2.10V
Explanation:
Using Nernst equation :
where,
= standard emf for the cell = +2.20 V
n = number of electrons in oxidation-reduction reaction = 6
= emf of the cell = ?
= concentration =
= concentration =
Now put all the given values in the above equation, we get:
The standard emf for the cell using the overall cell reaction below is +2.10 V

Answer:
a)The gravitational force would be twice as much as it is now
Explanation:
If the earth had twice its mass as it is now, the gravitational force between the sun and the earth would be twice as much as it is now.
According to Newton's law of universal gravitation "the gravitational force of attraction between bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
F =
G is the universal gravitation constant
m is the mass
r is the distance
let mass of sun = s
mass of earth = e
new mass of sun = s
new mass of sun = 2e
input variables;
F = ------ i
F = ------- ii
From the second equation;
2F =
2F = F
Therefore, the force will double.
Here is the answer that completes the statement above. We can study how galaxies evolve because THE FARTHER AWAY WE LOOK, THE FURTHER BACK IN TIME WE SEE. This means that the more we discover more about what's happening in the universe, the more we become curious to know how and when it began. Hope this helps.
