Please do all. Thanks. Instructions. Five problems on two pages, ten points each. Throughout, let R...
Please answer all parts. Thank you! 20. Let R be a commutative ring with identity. We define a multiplicative subset of R to be a subset S such that 1 S and ab S if a, b E S. Define a relation ~ on R × S by (a, s) ~ (a, s') if there exists an s"e S such that s* (s,a-sa,) a. 0. Show that ~ is an equivalence relation on b. Let a/s denote the equivalence class...
Let R be a commutative ring with no nonzero zero divisor and elements r1,r2,.. . ,Tn where n is a positive integer and n 2. In this problem you will sketch a proof that R is a field (a) We first show that R has a multiplicative identity. Sinee the additive identity of R is, there is a nonzero a E R. Consider the elements ari, ar2, ..., arn. These are distinct. To see O. Since R conelude that0, which...

please do this problem in matlab and show me the code. Thanks. please do this problem in Matlab and show me the code. Thanks. Problem #1: Circuits and linear-systems In the last HW you developed the governing equations for the “Wheatstone”-bridge circuit used extensively in engineering applications (shown below). B R R2 A D G m RA с E The resulting equations were solved for the output voltage and currents using the function: function [V_out, I_vector] =Wheatstone_bridge (v_in, R_vector) In...
Please show all your works. Thanks. 2) Let r(t) be the continuous-time signal x(t) t(0.97)' [a(t)-u(t-100)| where u(t) is the unit step function. We sample r(t) with a sampling period of T 0.4 over ootoo to obtain r/n]. Assume that the sample for n 0 is taken at t 0. We then use sinc interpolation to generate Tr(t) from xml a) Plot r(t) using MATLAB over the smallest range that includes all nonzero values of r(t) b) Find r[n] c)...

Update now A B C D E F G H J K L M N O P Q R S OPERATIONAL & COST INFORMATION: For simplicity, base all calculations using 30 days in each month m OPERATIONAL DATA Grooming: The Groomer can...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
