一、单项选择题(每题1分,每题只有一个正确答案。) 1、某企业期末对存货进行定期检查并计提减值准备,其中不正确的是() A.待加工材料M账面成本高于市场售价,按二者的差额计提跌价准备 B.待销售商品N已发生跌价,但因该商品已经有订购合同且以合同价计算可变现价值高于成本,未计提减值准备 C.待销售商品W已发生跌价,但在可预见未来价格可以很快回升,未计提减值准备 D.待加工材料X发生跌价是由于该材料加工的产品发生跌价,按照该材料成本与其可变现净值的差计提跌价准备

(A)General triaxial stress ellipsoid in perspective view. (B)Views normal to each of the principal planes of the ellipsoid. (After W.D. Means,1976)

Lecture 5 a distribution is a collection of scores order from lowest to highest value on the horizontal (X)axis, and in terms of T-Test frequency on the vertical (Y) axis. A ormal distribution sometimes referred to as a bell curve has a distribution that forms the shape of a bell. All you need to know to plot the normal distribution is the mean and standard deviation of the data This lecture covers

We have seen that the work done by a force F on a particle is given by dw =. dr. If the work done by F, when the particle moves from any position TI to any position T2, can be expressed as, W12=fdr=-(V(r2)-V(1)=V-v2, (1) then we say that the force is conservative. In the above expression, the scalar

Example 2: (p175-12) resistor, capacitor, and voltage source=100cos300n are all in series. If the average power dissipated by the resistor is 150W and the rms capacitor voltage is 10v, determine R and C
