FIFO Example. You use the first in first out method where you assume the first item you buy is the first item you sell - i.e. items are in a queue You buy the first item for 100 and the second item for 200 - you then sell 1 item for 400. At balance date you would have: Sales of 400 Cost of Sales of 100 Profit of 300 Inventory of 200.
At nanometer size. Any device only a few nanometers in size is nanoscale. Nanotechnology is said to comprise elements less than 100 nanometers in size (100 nm). See nanotechnology and nanometer.
Nano means very, very small. When it comes to making your body work, nano-materials are very important. A nanometre is one millionth of a millimetre. Your fingernail is about one millimetre thick.There are a lot of nano-materials making up your finger nail! Nanotechnology scientists move atoms and molecules around to make amazing new technologies.Nanotechnology is already in products like sunscreen.our fingernail is about one millimetre thick.
