the original KE formula was proportional to mv^2 the 1/2 factor was added afterwards. What is the physical meaning of v^2? Thanks for your detailed explanation. 2015-03-25 11:25:53 补充： My definition of "s" in previous equations is x1-x0 not [(u+v)t]/2 . So I ...
Present Value (PV) of Annuity = (A÷ r) (1 –(1÷ (1 + r) ^ t)) Ordinary Annuity vs. Annuity Due: What is the Difference? When calculating the present value (PV) of an annuity, one factor to consider is the timing of the payment. Ordinary Annuity→ Cash Flows Received at End...
As long as this factor is not dramatically influenced by changes in the apparent contact pressure p or the sliding velocity v, a plot of the so-called depth wear rate wt (reduction in specimen height per testing time) against the pv-product should show a nearly linear relationship, according...
In order to find Future Value which formula is correct to calculate from PMP point of view 1. FV=PV(1+r)n where n is the power of (1+r) and PV is Present value, r is rate of interest & n is time period i.e number of years 2. FV=PV(1+r/100)n where n ...

present valuefactor equal to the formula 1/(1 - r)n, where n is the number of years from the valuation date to the cash flow and r is the discount rate. For business valuation, n should usually be midyear, i.e., n = 0.5, 1.5, . . . ...
The foundation here is thetime value of money, i.e., that $100 today is worth MORE than $100 in 1-2 years from now because you could invest that $100 today and earn more by then. Yes, there’s also inflation, but that’snotthe key factor; in an environment with 0% inflation, ...
At 3 s, PV2 experiences partial shading with an irradiance of 1000 W/m2 and a shading factor βsh2 = 0.8. At 7 s, PV1 experiences partial shading with an irradiance of 800 and a shading factor βsh1 = 0.7. The experimental results are shown in Figure 19 below.FIGURE 19 Open in ...

The cash flow is discounted by the exponential factor. E. Dirty Pricing The clean price of a bond does not include the accrued interest to maturity of the coupon payments. This is the price of a newly issued bond in the primary market. When a bond changes hands in the secondary ...
