Problem 7: Diffusion. Crossing a membrane by simple diffusion can be distinguished from facilitated diffusion because: If the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane.
The second way to calculate compound interest is to use a fixed formula. The compound interest formula is ((P*(1+i)^n) - P), where P is the principal, i is the annual interest rate, and n is the number of periods. Using the same information above, enter Principal value into cell A1 and 1000 into cell B1.
For any given interest rate and compounding frequency, an equivalent rate for any different compounding frequency exists. Compound interest may be contrasted with simple interest, where interest is not added to the principal (there is no compounding). Compound interest is standard in finance and economics, and simple interest is used infrequently (although certain financial products may contain elements of simple interest).
