Homework Answers
initially,
a=10m
perimeter=6a=60m
after scaling,
a=2m
hence,perimeter=12m (decreases 5 times)
(decreases
25 times)

Engineering Mathematics 1 Page 3 of 10 2. Consider the nonhomogeneous ordinary differential equation ry" 2(r (x - 2)y 1, (2) r> 0. (a) Use the substitution y(x) = u(x)/x to show that the associated homogeneous equation ry" 2(r (x - 2)y 0 transforms into a linear constant-coefficient ODE for u(r) (b) Solve the linear constant-coefficient ODE obtained in Part (a) for u(x). Hence show that yeand y2= are solutions of the associated homogeneous ODE of equation (2). (c) Use...

B Frequency Response Modeling Frequency response modeling of a linear system is based on the premise that the dynamics of a linear system can be recovered from a knowledge of how the system responds to sinusoidal inputs. (This will be made mathematically precise in Theorem 13.) In other words, to determine (or iden- tify) a linear system, all one has to do is observe how the system reacts to sinusoidal...

Date Laboratory Exercises Using a molecular modeling kit, construct models of each of the compounds in the tables below. Complete the following three tables by first drawing a simple sketch of the molecule showing which atoms are attached to each other, the number of bonds between each pair of atoms, and any nonbonding electrons. Then, draw the molecule again showing the actual shape and the angles between the atoms as accurately as you can. The first one has been completed...

Dont know how to find wetted perimeter and area
3. The following Figure shows a liquid-to-air heat exchanger in which air flows at 50 m/h inside a rectangular passage and around a set of five vertical tubes. Each tube is a 1/2-in steel tube with a wall thickness of O. 049 in. The air has a density of 1.15 kg/m3 and a dynamic viscosity of 1.63 x 105 Pa.s. Compute the Reynolds number for the air flow. All dimensions in...

Problem 2: Modeling inseet population dynamies The use of arrays and matrix algebra are ideal for modeling population dynamics of organisms. If n) is computed from represents the number of organisms at time t, then the number at a later time, t+1, can be n(t+1) An(t). The array (vector, n) consists of the nurnber of females in each age class, and the array (matrix, A), called a Leslie matrix, is the survival- replacement matrix. Multiplying the...
