GROUP A MODEL ANSWER Howard et al.‚ Temperature-induced structural changes in CaCl2‚ CaBr2 and CrCl2: A synchrotron X-ray powder diffraction Phys. Rev. B 72‚ 214114 (2005). DO NOT PLAGIARISE THIS MODEL ANSWER Paragraph 1 This article concerns about 2 polymorph structures that is associated with temperature-induced structural transitions. One of the structure being studied is the orthorhombic structure‚ or sometimes referred to as the calcium chloride structure‚ that is observed before the transition

Physics 12 - Circular Motion Extra Problems 1. A 1400 kg car is travelling at 25 m/s on a circular hill of radius 210 m. What is the normal force on this car at the top of the hill? [pic] [pic] 2. In an amusement park‚ a 2.8 m radius “drum” rotates such that a person does not fall when the “floor” drops away. [pic] If the coefficient of friction between the person and the wall is 0.35‚ what is the maximum period of the rotation so that a person will not fall? A. 2.0 s B. 3.4 s C.

Find the electric field strength at the mobile location. Also find the power flux density Φ in w/m2 for users along the horizon. b. Repeat for the two-ray model‚ assuming a tower height of 40 meters‚ a mobile height of 2 meters‚ and a plane earth approximation. Assume the transmitted signal is verticallypolarized‚ and that the earth reflection coefficient magnitude is 1. c. Plot both power flux densities versus d on log-log scales‚ over a range from 100 meters to 10 kilometers. You should see scalloping

Kirchhoff’s laws (see also Kirchhoff’s laws for other meanings of that term). Both of Kirchhoff’s laws can be understood as corollaries of the Maxwell equations in the low-frequency limit -- conventionally called "DC" circuits. They serve as first approximations for AC circuits. Kirchhoff’s Current Law This law is also called Kirchhoff’s first law‚ Kirchhoff’s point rule‚ or Kirchhoff’s junction rule (or nodal rule). The principle of conservation of electric charge implies that: At any node

VIBRATION MEASUREMENT In some practical situations‚ it might be difficult to develop a mathematical model of the system and predict its vibration characteristics through an analytical study. In such cases‚ we can use experimental methods to measure the vibration response of the system to a known input. This helps in identifying the system in terms of its mass‚ stiffness‚ and damping. In practice the measurement of vibration becomes necessary for the following reasons: 1. The increasing demands

Accounting Estimate • Accounting estimate – An approximation of a monetary amount in the absence of a precise means of measurement. This term is used for an amount measured at fair value where there is estimation uncertainty‚ as well as for other amounts that require estimation.
