Explanation;
Writing scientific notation :
- Move the decimal to the left side until single digit of number remains before the decimal.
- Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
- For Example:
Radius of the sun = 696,000.0 kilometer
Radius of the sun can also be written as = 
Size of bacterial cell = 
millimeter
Size of bacterial cell can also be written as =

<span>The answer is C. Earth movements can origin rocks to be intensely suppressed or clutched. As an outcome, the rocks are heated and put below unlimited pressure. They do not dissolve, but the minerals they cover are altered chemically, making metamorphic rocks.</span>
Answer:
444 L
Explanation:
According to Archimedes the buoyancy force is equal to the weight of the displaced substance. In this case, the displaced substance is Air. So to calculate the lifting power of Helium, start with the weight of air in volume
Since the Helium itself has weight, we need to use the difference in density between air and helium.
We know that the density of air is 1.2 
Density of Helium is 0.1787
To lift a object of 1 pound which is equal to 0.453 kg we need 
helium There is 1000 liters in a
So the required volume of helium= 0.444×1000=444 L
