have you ever thought of the size of an ant and said that ant will only ever know my backyard? I mean the size of the ant is so small that it will only ever go around my backyard in its life...for example. Just after your thoughts on the size of humans. If you could imagine zooming out of the earth an infinate amount of times what do you think you would see? Im religious and really dont believe there are other life forms out there but its like how small and insignificant are we when compared to the size of the universe...

calcuate the pressure that is being exerted onto the meat as it is being sliced?- P=f/a= 50/0.002=25,000
if the knife gets rusty, it's cutting surface area and hence applied pressure will be affected, and the knife will not cut as well. use your own numbers to show how, even though the same force is being applied as above, the knife will not cut as well.
how do u do this problem? choose any number less than 0.002m^2.
