The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km). The total volume of the sun is 1.4 x 1027 cubic meters.
Answer:
B.
Explanation:
The up and down movement of gases and liquids caused by heat transfer is convection.
The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high
will have:
Option B. A low
and a high 
This characteristic can be explained as:
- The concentrations of
and
are inversely dependent on each other so when the concentration of raises then the concentration of
drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
![\rm pH = \rm - log \rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%20pH%20%20%3D%20%5Crm%20-%20log%20%20%5Crm%20%5BH%5E%7B%2B%7D%5D)
From the formula, it can be deduced that when the concentration of
is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:

From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then
is low.

1.5*9.8*1.2
since the formula is force * distance.
1.2 is the distance. the force is gravity on the object (1.5*9.8)
The answer is 17.64 J . (18 J with sig figs)
