The Clausius equation of state describes the behavior of a certain fluid: P(V ? b) = RT with b = 10?5 m3/mol. For this fluid, C ? P =25 + 4 10?2 T J/(mol K) (a) Derive an explicit algebraic expression for the CP of the fluid, valid at any pressure. when organizations are successful, the values, ideas, and practices that helped attain success become institutionalized. question 6 options: true false The assembly is made of the slender rods that have a mass per unit length of 7 kg/m. Determine the mass moment of inertia of the assembly about an axis perpendicular to the page and passing through point O. what is the molar solubility of lead sulfate in 1.0 103 m na2so4? solubility product constant pbso4 ksp = 1.8 108 (a) 1.8 102 (c) 1.8 105 (b) 1.3 104 (d) 5.0 106 a sine wave will hit its peak value ___ time(s) during each cycle.(a) One time(b) Two times(c) Four times(d) A number of times depending on the frequency To assess the correctness of a segmentation, a set of measures must be developed to allow quantitative comparison among methods. Develop a program for calculating the following two segmentation accuracy indices:(a) "Relative signed area error" is expressed in percent and computed as:In matlab: To assess the correctness of a segmentawhere Ti is the true area of the i-th object and Aj is the measured area of the j-th object, N is the number of objects in the image, M is the number of objects after segmentation. Areas may be expressed in pixels.(b) "Labelling error" (denoted as L error ) is defined as the ratio of the number of incorrectly labeled pixels (object pixels labeled as background as vice versa) and the number of pixels of true objects sigma i = 1, N, Ti according to prior knowledge, and is expressed as percent. If 0. 25 L of H2(g) are collected at 25 C and 1. 1 atm. What will the pressure of the gas be if the temperature of the gas is increased to 30 C at a constant volume? write the complete nuclear equation for the bombardent of a be9 atom with an particle to yield b12 . show the atomic number and mass number for each species in the equation. T/F: management is the process of guiding the development, maintenance, and allocation of objectives. What are the minimum numbers of keys and pointers in B-tree (i) interior nodes and (ii) leaves, when: a. n = 10; i.e., a block holds 10 keys and 11 pointers. b. n = 11; i.e., a block holds 11 keys and 12 pointers. a frictionless cart attached to a spring vibrates with amplitude a.part complete determine the position of the cart when its kinetic energy equals its elastic potential energy. Suppose 2 landowners share water from a common underground aquifer. They can choose to take 0, 1, or 2 units of water each year for the next two years. In both years, the value of the 1st unit of water is $7 and the value of the second unit of water is $5. There are 4 units of water altogether. The cost of extracting water is $1 per unit. Finally, if there is an odd number of units left in the second year, assume the odd unit gets split between the 2 landowners, each getting half the value and paying half the cost. How much water will each landowner take in the 1st year if he chooses the amount of water to maximize his consumer surplus?a. 2 unitsb. 1 unitc. 0 units find f. f''(x)=x^3 sinh(x), f(0)=2, f(2)=3.6 A point charge q1=5.00Cq1=5.00C is held fixed in space. From a horizontal distance of 7.00 cm, a small sphere with mass 4.00103kg4.00103kg and charge q2=+2.00Cq2=+2.00C is fired toward the fixed charge with an initial speed of 36.0 m/sm/s. Gravity can be neglected.What is the acceleration of the sphere at the instant when its speed is 24.0 m/sm/s? Make the indicated trigonometric substitution in the given algebraic expression and simplify (see Example 7). Assume that 0 < theta < /2. 25 x2 , x = 5 sin(theta) into the killing seas ar test true or false if a has a simple circuit of length 6 so does b is isomorphic calculate the amount of heat required to heat 725 g of water from 22.1oc to 100.0oc.

He wants the pond to have a deck of equal width around it. The lengths of the interior deck sides are the same length, and the lengths of the exterior sides are the same. given the function f ( t ) = ( t 5 ) ( t 7 ) ( t 6 ) its f -intercept is its t -intercepts are
