Answer:
C. C, because it’s the highest of all four and C is 2,5 which is medium but the highest one.
Answer:
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
Ocean currents determine the various directions of wind movement.
<h3>What is ocean current?</h3>
Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.
Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

Explanation:
It is known that molecular formula of potassium dichromate is 
. As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.
Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.
= 0 (as the molecule is neutral)
= 0
2 + 2x - 14 = 0
x = +6
Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
