Question

What am I doing wrong here?

Answer 1

This is my work

Answer 2

@Angle @Shadow @SmokeyBrown @TheSmartOne

Answer 3

a couple of issues here

1 μm = 10^(-6) meters

we are working with square units so we have to square both numbers on the conversion factor

1 μm^2 = (10^(-6))^2 meters^2

therefore 2.9 * 1 μm^2 = 2.9 * (10^(-6))^2 meters^2

finally, your answer must be in three significant figures, not 2. the solution you have given is only 2 significant figures so you need to put an extra 0 at the end

Answer 4

so 2.90 * 10^-8

Answer 5

Answer 6

2.90 x 10^-12
