Homework Statement As an exercise, a woman pulls on both sides of a stiff spring to work on her chest muscles. The spring stretches 7.2 cm when she pulls on it with a force of 111 N. She then makes a greater effort and stretches the spring 17 cm. a. Write an equation relating the force, F...

So I converted 0.18 centimeters to micrometers and got 1800 micrometers. So then, I just take 1800 micrometers divded by 9.45 micrometers to get how many will fit across? 1800/9.45. I came up with 190.476, but since I can only have two significant figures in my answer, it would be 190 algae...

Couldn't I just convert 9.45 micrometers to centimeters and divide by 0.18 cm to get the thickness between the gaps in terms of algae thicknesses?

Homework Statement a. How wide is the gap between tiles in centimeters? b. How wide is the gap in inches c. How many algae-thicknesses is the gap between tiles Homework Equations The Attempt at a Solution First off, I just want to know if I did a and b correctly. To set up...

So you think that this setup is fine?

Thanks for the input. Good to meet you.
