What is the pressure exerted by a force of 900 newtons on an area of 60 cm^2?

Answer 1

Amelia Adams

First we convert the #cm^2->m^2#

#60cancel(cm^2)xx(1m^2)/(100^2cancel(cm^2))=0.0060m^2#

Then we divide #p=F/A#

#p=(900N)/(0.0060m^2)=150000N/(m^2)=150000Pa=150kPa#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
