2009年4月23日 · The PERT (Program Evaluation and Review Technique) formula is a mathematical model used in project management to estimate the minimum time needed to complete a project. It takes into account the optimistic, most likely, and pessimistic time estimates for each task in a project and calculates the expected completion time.

2009年6月20日 · Hi P*e^(rt) = Accumulated amount of money Principal e logaritm rate time is for continuous compounding of rate. F=A(((1+i)^n-1)/i) and this one works for savings that are made frequently like every month or so but only with annual compounding of rate. is there any way to...

2016年2月26日 · This formula we've been using recently, I don't understand where it comes from. Homework Equations T = 2pi * sqrt(m/k) The Attempt at a Solution Hooke's law: F = -kx E(total) = .5mv^2 + .5kx^2 Circumference of a Circle: C = 2 * pi * r I figure these piece together, but I don't understand how.

2019年9月5日 · i have a neobydium magnet of grade n40 , the diameter of magnet is 15mm and thickness is 10 mm , now i want to calculate the pull force between this magnet and a steel plate when there is no gap between them ; & in second case i want to calculate the pull force when i put a 0.15mm copper plate...

2008年4月22日 · but it was solved in class, and the teacher said we were supposed to use that special formula, 2*v1*v2/(v1 + v2) in all situations similar to this, that is, when the problem asks us to find the average of velocities when the distance …

2004年11月20日 · The formula for psi of static pressure is the height in feet times approximately .43 (or divided by approximately 2.33). Multiply the height of the water above any point by the area of the tube at that point and you can determine …

2011年11月24日 · Also, this formula allows for an even number of interference fringes in the central peak (consider d/a = 2.5, 2(2.5 - 1) = 4), is that possible? Physics news on Phys.org Fiber image transmission technology for minimally invasive endoscope developed

2010年5月12日 · Hi all. I'm just wondering if it is possible to calculate the resistance in a coil without the amperage value? I've got voltage,coil-diametre, amount of turns, coils material type. The only way i think it is possible if i set a ampmetre into the circuit. is there any way? Thank you.

2016年7月31日 · torque x (angular velocity) has unit of Nm(rad/s), is the formula given wrong? Angles do not have a dimension in the way that mass, time, etc. do. Consider e.g. that a circular arc of radius r and angle θ has length rθ.
