Question

Each droplet that you sneeze is approximately 7 x 10-3 mm in diameter. If you wear an N95 mask, which filters virus particles as small as 8 x 10-5, will you sufficiently protect those around you? Explain your reasoning.

Answer 1

Yes, 7 x
`10^(-3)` in standard form is 0.007mm

8 x
`10^(-5)` in standard form is 0.00008 mm. The mask will catch particles that are much smaller than 0.007 in diameter.
