Which is larger: the number of meters across the Milky Way, or the number of cells in all humans? Explain or show your reasoning.

Some useful information: The Milky Way is about 100,000 light years across; There are about 37 trillion cells in a human body; One light year is about 10^16 meters; The world population is about 7 billion.

there are more cells in all humans than the number of meters across the Milky Way

Step-by-step explanation:

Here we are told that 1 light year is equivalent to:

We also know that the diameter of the Milky Way is

Therefore, the diameter of the Milky Way in meters is:

On the other hand, the world population is about 7 billion:

Every human body has about 37 trillion cells, which corresponds to

Therefore, the total number of cells in all humans is

The second number is larger: therefore, there are more cells in all humans than the number of meters across the Milky Way.

answer4 to the second power is 16

and 4 to the third power is 64,

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
