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.
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest. Compound interest is standard in finance and economics. Compound interest may be contrasted with simple interest, where interest is not added to the principal, so there is no compounding. The simple annual interest rate is the interest amount per period, multiplied by the number of periods per year.
