Question

The mass of a small virus is 10^-20 kg. The mass of an average human cell is 10^-12 kg. Which of the two has lesser mass? how many less is it?

Answer 1

For this case we have:

$10 ^ {- 20}$, we must run the decimal point 20 spaces to the left.

$0.00000000000000000010 \ kg$

$10 ^ {- 12}$, we must run the decimal point 12 spaces to the left.

$0.000000000010 \ kg$

Thus, it is observed that the mass of a small virus is smaller!

We subtract and obtain:

$10 ^ {-11}$

ANswer:

The mass of a small virus is less!

Answer 2

Answer: -10kg

Step-by-step explanation:

10-20 =-10

10-22 =-12

-10 is lesser
