Answer:
Mercury
Essentially because Mercury is closest to the Sun, when taking an average over time, Mercury is the closest planet to the Earth, and - in that measure - it is the closest planet to each of the other planets in the Solar System.

Answer:
<h3>1/16</h3>
Explanation:
According to the coulombs law, the force existing vetween the ions is expressed as;
F = kQq/r² .... 1
Q and q are the ions
r is the distance between the ions
If the distance between the ion is quadrupled, then;
F2 = kQq/(4r)²
F2 = kQq/16r² ... 2
Divide equation 2 by 1;
F2/F = kQq/16r² ÷ kQq/r²
F2/F = kQq/16r² × r²/kQq
F2/F = 1/16
F2 = 1/16 F
Therefore the coulombic force between two ions is reduced to<u> 1/16 </u>of its original strength when the distance between them is quadrupled.

Answer:
4. The voltage is reduced by a factor of 2
Explanation:
The relationship between voltage, current and resistance in a circuit is given by Ohm's law:
V = RI
where
V is the voltage
R is the resistance
I is the current
In this problem,
the resistance in the circuit is halved: R' = R/2
the current is constant : I' = I
So the new voltage is
![V' = I' R' = I (\frac{R}{2})=\frac{1}{2} (IR) = \frac{V}{2}](https://tex.z-dn.net/?f=V%27%20%3D%20I%27%20R%27%20%3D%20I%20%28%5Cfrac%7BR%7D%7B2%7D%29%3D%5Cfrac%7B1%7D%7B2%7D%20%28IR%29%20%3D%20%5Cfrac%7BV%7D%7B2%7D)
so the voltage is reduced by a factor 2.
Answer:
2
Explanation:
Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
